Hi readers! I hope you all are doing well and learning and exploring new things. We live in an era where technology is growing faster every day. Prototyping is the rough and simple model of the product that innovators want to introduce into the market. They perform tests, and if the results are unsatisfactory they fix the problem and reprocess them faster to beat the competition in the market. Rapid prototyping becomes crucial for the foundation of the development of modern products. Rapid prototyping sped up the path from the initial steps to the formation of the product. Rapid prototyping is highly demanded as compared to traditional methods because it is cost-effective, saves time, consumes fewer resources, and produces several products rapidly and efficiently.
In the early days, the process of manufacturing products took time, was costly, and used high resources. Little modification in the product was not easy because it consumed more resources and was costly. Rapid prototyping solved all these issues efficiently when it evolved in the early 20th century. It has become advanced in computer-aided designs (CAD) and 3D printing. It allows companies to bring new products into the market rapidly. It has diverse applications in industry, automation, health care, electronics, aeroscopes, and software development.

Hi, friends I hope you are all well and doing your best in your fields. Today we can discuss the main topic which is acceleration. Acceleration is a central idea in physics that is key to understanding the motion of objects. It is the rate at which an object changes its velocity with time. This variation can take place either as a change in speed or direction. In simpler words, it tells us how fast the velocity of an object is changing along a particular track. As objects move, they may accelerate by gaining, losing, or changing direction. Many concepts in physics and engineering depend on understanding acceleration, such as the movement of celestial bodies to what happens to everyday objects. It is also vital in explaining why objects move, how forces act on them, and the basic principles governing their motion.
In layman’s language, you can experience acceleration when your car speeds up on a highway when an athlete suddenly changes his/her running direction or even if you throw any ball upwards. By studying the acceleration concept, physicists and engineers can predict and explain motion, design efficient transportation systems, and develop technologies based on controlled motion and velocity changes.
Acceleration is simply defined as the rate at which velocity changes in a given period. Velocity is a vector quantity because it has both magnitude and direction; hence, acceleration is also a vector component. The International System of Units (SI) uses meters per second squared (m/s²) as its standard unit of acceleration.
Mathematically, acceleration can be expressed by:
a = Δv/Δt
Where:
∆v( Delta-v ) reflects the change in velocity,
∆t( Delta t ) reflects the change in time.
When an object’s velocity changes uniformly, it undergoes constant acceleration. In contrast, if the rate at which its velocity alters fluctuates, then non-uniform acceleration occurs.
Several types of acceleration can be classified based on their characteristics and context of occurrence:
Uniform acceleration is where the rate at which a body’s velocity changes over time remains the same. Such a kind of motion is common in many theoretical studies, making it an easier method to describe motion.
One instance of uniform acceleration is when an object falls freely in a vacuum under gravity with no other forces acting on it. In such a case, it will accelerate downwards due to gravitational pull at approximately 9.8 m/s².
Non-uniform acceleration refers to when there are varying velocities during different times. This often takes place in real-life instances whereby various forces may be acting on an object at different times. For example, non-uniform acceleration happens to a car that speeds up and slows down in traffic. Alterations in the forces exerted on this vehicle (like gear position or road conditions) make for fluctuations in its rate of change of speed.
In circular motion, there are two components of acceleration: tangential and centripetal. Tangential acceleration occurs whenever there is a change in speed along any point around the circumference. Tangential acceleration is experienced when there is an alteration in the speed along the circular path. On the other hand, centripetal acceleration points towards the center of a circle and helps to keep the object on its curved course. The formula for centripetal acceleration ac can be given as:
ac = v2/r
Where:
( v ) is the velocity of the object along the circular path,
( r ) is the circle’s radius.
Alternatively, in terms of angular velocity (ω) and radius ( r ), we can also write centripetal acceleration:
ac = r ω²
This implies that centripetal acceleration will always point to the center of a circular path and is responsible for altering the direction of an object’s velocity without affecting its magnitude (speed). This concept is important in understanding circular motion because it is related to the force-directed inward that keeps objects following curved paths, which are shown by Newton’s laws of motion.
In physics, tangential acceleration refers to how fast an object’s rate or speed changes as it travels along a curved path. Unlike linear acceleration, which varies an object’s speed on a straight trajectory, tangential acceleration affects the speed of an item moving along a bent direction.
In rotational movement or while an item actions alongside a round route, its pace modifications no longer only in significance but additionally in the course. Tangential acceleration (at) in particular refers back to the factor of acceleration that causes modifications in the pace (importance of speed) of the item. It is directed along the tangent to the route of motion and is measured in meters in line with second squared (m/s²).
At = d|v| /dt
Where |v| denotes the magnitude of the velocity vector v.
Tangential acceleration plays a vital function in expertise round and rotational movement. For instance, whilst an automobile negotiates a curve on a tune, its speed adjustments are not handiest due to speed changes (tangential acceleration) but additionally due to changes in the path (centripetal acceleration). Together, these accelerations determine how easily and predictably an object can navigate curves without skidding or losing manipulation.
In precis, tangential acceleration describes how the speed of an item adjusts along a curved path, offering crucial insights into the dynamics of rotational and round motion in physics.
Centripetal acceleration is the acceleration that continues an item transferring in a circular route. It is directed in the direction of the center of the circle or the axis of rotation, perpendicular to the item’s velocity vector. In many sensible situations, centripetal acceleration arises while an item moves alongside a circular trajectory, together with a car navigating a curve, a planet orbiting a celebrity, or a satellite TV for pc circling the Earth.
Centripetal acceleration is continually directed toward the center of the round course and is chargeable for converting the route of an item’s pace without altering its velocity (value of speed). It is a vital idea in information circular movement and is carefully related to the centripetal pressure required to preserve the object’s round path, as described with the aid of Newton’s laws of motion.
In summary, centripetal acceleration is the acceleration that acts toward the center of a round direction, making sure that gadgets preserve their trajectory and do now not deviate into an instant line.
The mathematical representation of acceleration can be explored through various equations and principles, often linked to Newton’s laws of motion.
For motion with uniform (constant) acceleration, we use a set of kinematic equations to describe the relationships between displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t). These equations are fundamental in classical mechanics and are used to solve various problems involving motion.
v = u + at
According to this equation, the final velocity (v) is equal to the initial velocity (u) plus the product of acceleration (a) and time (t).
s = ut + ½ at²
This equation provides the displacement (s) of an object based on its initial velocity (u), time (t), and acceleration (a).
v² = u² + 2as
This equation relates the final velocity (v), initial velocity (u), acceleration (a), and displacement (s). It is especially helpful in situations when time is unknown.
These kinematic equations assume constant acceleration and are widely used in physics to analyze the motion of objects.
Classical mechanics is based on Newton’s second law of motion. Establishes the relationship between force (F), mass (m), and acceleration (a);
F = ma
This equation shows that the force acting on an object is equal to the product of its mass and velocity. It means that the velocity of an object is inversely proportional to its mass and directly proportional to the applied force. This principle is important for understanding how forces affect processes.
For example, if a net force is applied to a car, its acceleration can be determined by dividing the force by the weight of the car. Conversely, the required force can be calculated by determining the desired magnitude and velocity.
When an object acts in a circular direction, it experiences centripetal acceleration, which is directed toward the center of the circle. This acceleration is essential to trade the direction of the item's speed, keeping it on the circular course. The following yields the centripetal acceleration (ac ) ;
ac = v²/r
where:
(v) is the velocity of the object along the circular path,
(r) is the circle’s radius.
This equation suggests that centripetal acceleration increases with the square of the velocity and reduces with an increase inside the radius of the circular course. It is crucial for understanding the dynamics of items in circular motion, like cars taking a turn or planets orbiting the Sun.
Example:
Suppose a car traveling at a speed of 20 m/s around a curve with a radius of 50 meters. The centripetal acceleration ( ac ) Can be calculated using the formula:
ac = v²/ r
ac = 20²/ 50
ac = 400/50
ac = 8m/s²
The car exploits a centripetal acceleration of 8 m/s² in the direction of the circular path’s center.
In calculus, acceleration can be expressed as the derivative (d) of velocity concerning time. If velocity (v) is a function of time (t), then acceleration (a) is given by:
a = d v / dt
This differential form provides a precise way to describe acceleration at any given instant. For cases where velocity is not constant, integrating acceleration over time can determine the change in velocity;
v = ∫a dt
Similarly, if acceleration itself is a function of time, position, or velocity, the motion of the object can be analyzed using differential equations. Solving these equations yields detailed information about the object's velocity and position over time.
In particular, the uniform acceleration with which the bodies falling freely near the Earth’s surface act is called gravitational acceleration or Gravitational acceleration is the acceleration associated with the force of gravity of a body, for example, the Earth. Estimates put it at 9. 8 m/s² and this is abbreviated as ‘g’. The equations of motions for objects under gravitational acceleration are as follows; very much like kinematical equations, the only changes that occur is the use of (a) as (g).
For an object in free fall, the equations become:
Final velocity: v = u + gt
Displacement: s = ut + ½ gt²
Velocity-displacement: v² = u² + 2gs
These equations are very useful for solving problems on the motion of objects under the force of gravity like a falling object or a projectile.
Gravity acceleration is simply the acceleration that an object goes through when under the effect of gravity. On the surface of the earth, the acceleration due to gravity is roughly about 9. 81 meters per second squared ( 9. 81 m/s² ). This value gives the rate at which objects fall towards the center of the earth because of the force of gravity.
Of the two types of acceleration, the tangential acceleration deals with acceleration in the plane of motion or along the circle’s circumference while radial acceleration refers to the acceleration that is directed toward or away from the center of the circle. Tangential acceleration (at) is an acceleration in the radial direction it is incorporated into the change speed of the object in the circular path and radial or centripetal acceleration (ar) is towards the center to reverse the direction of the velocity vector head.
If the angular velocity (ω) of an object in circular motion changes over time, the tangential acceleration can be expressed as
If the angular velocity (ω) of an object in circular motion changes over time, the tangential acceleration can be expressed as:
at = r dω/ dt
where (r) is the radius of the circular path.
The total acceleration (a) is the vector sum of tangential and radial acceleration which is represented by The mathematical formula for the same is;
a = √at² + ar²
These components are significant in analyzing objects in a non-uniform circular motion because it is applicable in real-life situations like cars moving at different speeds on curves.
Concluding, it is necessary to state that acceleration in mathematics is described by several equations and principles that determine the change of velocity in an object throughout time. Some of them are the kinematics equation for the impact of uniform acceleration, Newton’s second law, centripetal acceleration for circular motion, differential calculus for non-uniform acceleration, specific instances like gravitational acceleration, and so on. For students, these tools are indispensable necessities for finding solutions to various problems and for understanding the motion of various objects in situations of their application.
Accelerometers are therefore instruments that are used in the measurement of acceleration. It is used in almost every technological field; right from mobile phones to space shuttles. Accelerometers work based on the principle that they generate an electrical signal that is proportional to the force exerted on a test mass in the device under the effect of acceleration. Below are some of the common types of accelerometers;
These measure changes in capacitance due to the displacement of a test mass when acceleration happens. capacitive accelerometer is a kind of accelerometer which its
working is based on capacitance change as a result of acceleration.
Capacitive accelerometers refer to the devices that are commonly used in the measurement of acceleration through capacitance variations. They consist of two main components: a proof mass and a fixed capacitor structure is used. The proof mass is often, but not necessarily, small and is free to move in a direction perpendicular to the direction of the force being measured by the interferometer, and is attached between two springs. As the accelerometer goes through acceleration, the proof mass shifts concerning the fixed plates of the capacitor and results to a change in capacitance.
Based on the above results, it can be noted that the change in capacitance is directly proportional to the acceleration applied to the device. This can be measured electronically and converted into an acceleration value depending on calibration value and signal processing measures.
The above capacitive accelerometers' main characteristics and benefits are high sensitivity, low power consumption as well as an extended measurement range. They are popular in many demands for the measurement of acceleration including automotive technology (For example air-bag systems), aerospace engineering (For instance, flight control), handheld devices (For instance, the built-in accelerometer in every smartphone for tilting), and large machinery (For instance vibration measuring).
These produce an electric charge as a result of mechanical stress from acceleration. A piezoelectric accelerometer, as a kind of accelerometer, is an instrument that can define acceleration by using the piezoelectric phenomenon.
Piezoelectric accelerometers are devices used to measure accelerations, vibrations, and shocks for many applications. They use the working of piezoelectric effect which states that acceleration is transformed into electrical charge. These accelerometers include a piezoelectric crystal, usually of quartz or ceramic, whose output voltage depends on the acceleration.
The important characteristics of piezoelectric accelerometers are high or greater sensitivity, wide frequency range, robust structure, and insensitivity to high temperatures. These applications are in automobile manufacturing, aerospace, manufacturing industries, and in the monitoring of structures.
Piezoelectric Crystal: The principal part of a piezoelectric accelerometer is a piezoelectric crystal with quartz or ceramic material. When the accelerometer does move and thus, apply inertial force on it, then, the crystal elongates or contracts slightly.
Generation of Electrical Charge: As per the piezoelectric effect, the above-mentioned deformation results in the formation of an electrical charge on the surface of the crystal. The degree of charge is proportional to the acceleration applied to the accelerometer device.
Measurement and Output: The generated electrical charge is usually intensified and analyzed through the use of electronics within the accelerometer. This leads to an output signal (generally voltage) proportional to the acceleration that the device is subjected to.
Piezoelectric accelerometers are provided in several formats and orientations single, dual, and triaxial depending on the utilization of the device. They are widely applied for vibration measurement in rotating and other machinery, structure monitoring, automotive safety by crash testing, and seismic application.
MEMS accelerometers are small-size, low-cost acceleration sensors commonly used in portable electronics. They employ minuscule mechanical elements that bend with acceleration and change the various electrical currents. MEMS accelerometers are electrical devices that are quite small and are employed for measuring accelerations.
MEMS accelerometers as small, integrated devices that measure acceleration using microfabrication technology. They can be classified into the family of micro-electromechanical system sensors, often abbreviated as MEMS, where mechanical components include springs and proof masses as well as electronic components like capacitors and resistors and are all integrated into one chip.
Microfabricated Structure: Generally the MEMS accelerometers have a micro-fabricated structure; in most common configurations there is a proof mass that is attached to the substrate by springs. The proof mass is displaced relative to the package frame under the action of external forces that cause acceleration.
Sensing Principle: Acceleration leads to forces on the proof mass causing it to move a certain distance away from the springs. This displacement is measured with several sensors, for example, capacitive sensors or piezoresistive sensors.
Signal Processing: Due to this movement of the proof mass an electrical signal corresponding to the acceleration is obtained. The signal is then amplified by integrated electronics which are provided in the specific MEMS chip to generate a readable output.
There are different types of MEMS accelerometers and they can be classified based on their axis; they can have single-axis, two-axes, or three-axes. They are used in a wide range of applications, including:
Consumer Electronics: Smartphones and tablets motion sensing, and gaming control equipment.
Automotive: Airbag: active and passive electronic systems concerning vehicle stability, and vehicle navigation systems.
Industrial: Machinery condition monitoring, attitude determination and control, and structure health monitoring.
Healthcare: Including fall detection gadgets, wearable health monitors, and health enhancers in the human body.
In the realm of special relativity, the concept of acceleration becomes more complex. As objects approach the speed of light, their mass effectively increases, requiring greater force to achieve further acceleration. The relativistic form of Newton's second law is used to account for these effects:
F = γ³ma
where:
γ is the Lorentz factor, given by ;
v is the velocity of the object,
c is the speed of light.
This equation shows that as v approaches c, γ increases significantly, making it increasingly difficult to accelerate the object further.
In general relativity, acceleration due to gravity is understood as the curvature of space-time caused by massive objects. Instead of viewing gravity as a force, general relativity describes it as the effect of space-time curvature on the motion of objects. The equations governing this curvature are given by Einstein's field equations:
Gμν = 8πG/c⁴ Tμν
where:
Gμν is the Einstein tensor representing space-time curvature,
G is the gravitational constant,
c is the speed of light,
Tμν is the stress-energy tensor representing matter and energy distribution.
In this framework, objects follow geodesics, which are the paths determined by the curvature of space-time. The acceleration of objects in a gravitational field is thus a manifestation of their motion along these curved paths.
In aerospace engineering, understanding acceleration is crucial for designing aircraft and spacecraft. Engineers must consider the accelerations experienced during various phases of flight, including take-off, cruising, maneuvering, and landing.
During the design of aircraft, engineers analyze the accelerations and forces acting on the airframe to ensure structural integrity and passenger comfort. This involves studying the effects of aerodynamic forces, thrust, and gravitational forces. Pilots also need to understand acceleration to perform safe and efficient maneuvers.
Spacecraft navigation relies heavily on precise calculations of acceleration. For example, during interplanetary missions, spacecraft use gravity assists (also known as gravitational slingshots) to change their trajectories and speeds. By carefully planning these maneuvers, mission planners can use the gravitational fields of planets to accelerate the spacecraft, saving fuel and reducing travel time.
In the automotive industry, acceleration is a key factor in vehicle performance, safety, and comfort. Engineers use the principles of acceleration to design better engines, braking systems, and suspension systems.
The performance of a car engine is often measured by its ability to accelerate the vehicle. Engineers design engines to provide optimal acceleration while maintaining fuel efficiency and reducing emissions. This involves optimizing the combustion process, transmission system, and overall vehicle weight.
Modern cars are equipped with advanced safety systems that rely on precise measurements of acceleration. For example, electronic stability control (ESC) systems use accelerometers to detect and correct skids or loss of control. Similarly, airbag deployment systems use accelerometers to detect sudden decelerations during collisions and deploy airbags to protect occupants.
In robotics, controlling acceleration is essential for achieving precise and efficient movements. Robots in manufacturing, healthcare, and exploration require accurate acceleration control to perform tasks effectively.
Industrial robots often operate in environments that require high precision and speed. To achieve this, robots use advanced control algorithms to manage acceleration and deceleration smoothly. This helps prevent mechanical wear and tear and ensures accurate positioning.
Medical robots, such as surgical robots, must operate with high precision to perform delicate procedures. Controlling acceleration in these robots is critical to avoid damaging tissues and to provide smooth and controlled movements.
Various experimental techniques are used to measure and analyze acceleration in different contexts. These techniques range from simple mechanical setups to advanced electronic systems.
One of the simplest ways to study acceleration is through pendulum experiments. By measuring the period of a pendulum's swing, one can calculate the acceleration due to gravity. For the simple pendulum, The period (T) is written as:
T = 2π √L/g
where:
( L ) is the pendulum’s length,
and ( g ) is the acceleration caused by gravity.
By measuring (T) and (L), the value of (g) can be determined.
Drop tower experiments involve dropping an object from a known height and measuring its acceleration as it falls. These experiments are often used to study the effects of microgravity and to test the performance of accelerometers. The object's acceleration can be analyzed using high-speed cameras or precise timing systems.
Computational methods, including numerical simulations and modeling, are used to study complex systems where analytical solutions are not feasible.
Finite element analysis (FEA) is a computational technique used to simulate and analyze the behavior of structures under various loads, including acceleration. FEA divides a structure into smaller elements and solves the equations of motion for each element. This method is widely used in engineering to predict the performance of complex systems.
In fluid dynamics, acceleration plays a critical role in the behavior of fluids. Computational fluid dynamics (CFD) is used to simulate the motion of fluids and the forces acting on them. By solving the Navier-Stokes equations, CFD can provide detailed insights into the acceleration of fluid particles and the resulting flow patterns.
Acceleration is a vital idea in physics that narrates how the object’s velocity varies over time. It is essential for understanding the dynamics of motion and has a wide range of applications in everyday life, engineering, technology, space exploration, and scientific research.
From the uniform acceleration of free-falling objects to the complex accelerations experienced by spacecraft, the study of acceleration provides insights into the forces and interactions that shape our world. By employing mathematical equations, experimental techniques, and computational methods, scientists and engineers can analyze and predict the behavior of systems under various conditions of acceleration. Understanding acceleration not only helps us comprehend the physical world but also drives technological advancements and innovations that improve our lives.
Hello friends, I hope you are all well and doing good in your fields. In the previous article, we can discuss the distance and displacement of the objects. Still, today we can talk about velocity because velocity provides information about the speed from which the object can be displaced from one point to the other point. Everything can be moved from one place to another with different speeds and velocities. To understand the speed or the motion of an object it is compulsory to understand the velocity. The concept of velocity is the cornerstone notion in the field of physics because it can provide information about the rate of change of displacement or position. Through speed and velocity, the object can be displaced but the speed is a scalar quantity because it can only provide the magnitude but the velocity is the vector quantity which can provide both magnitude and direction.
In dynamics, and kinematics it can play a very crucial role in understanding the motion of the displaced objects and also helps to understand the various physical phenomena related to the motion of an object. Simply speed and velocity are a combination but speed only provides the magnitude while velocity provides both the magnitude and direction of the moving object. Like kinematics, the notion of velocity is fundamental to understanding the motion of an object in mechanics.
Both speed and velocity describe the motion of an object, based on the idea that an object can be moved fast or slow. Speed and velocity help to identify the objects that can be moved fast or also those objects that can be moved slow. When two objects are displaced at the same time, the fastest object can reach its ending point and this object has high speed and velocity as compared to others. Now, we can start exploring the basic definition of velocity, its types, mathematical representation, examples, and the main difference between speed and velocity.
Velocity is defined as:
“The rate of the change of the position of the body with time or the rate of the change of displacement with time is termed as velocity.”
The main difference between speed and velocity is that speed is the rate of change of position in the unit of time but velocity is the rate of change of displacement in the unit of time.
Mathematical representations of velocity are written below:
Velocity = displacement x time
v =dt
there,
v represented velocity and d represented displacement and t represented the time.
This formula can also be written as:
d = vt
This formula shows that the body can be displaced with some velocity at the unit time.
The SI unit of the velocity is the same as the speed which is meter per second and is written as ms (ms-1).
Dimension of velocity SI unit are written below:
ms-1 = LT-1
There, L is the dimension for m and T-1 is dimension or s-1.
Average velocity can be defined as:
“ the ratio of the total change of position or displacement with the total time taken is termed as average velocity”
generally, the average velocity is the overall motion of the object that can be covered from one place to another with a unit of time.
Average velocity can be mathematically represented as:
vav = ΔdΔt
There, v represented the average velocity, Δd represented the rate of change in displacement and Δt represented the rate of change in time.
The SI unit of the average velocity is a meter per second and is written as ms (ms-1)
Dimension of average velocity SI unit are written below:
ms-1 = LT-1
There, L is the dimension for m and T-1 is dimension or s-1.
The direction of the average velocity of the displaced object is always in the direction of the displacement.
Some major limitations of the average velocity are given there:
Average velocity can't describe the motion of the object or body, the body or object may be do random motion or maybe it can do a steady motion. But the average can't tell about their type of motion.
Average velocity can't also provide information about the path in which the body can be displaced because the path may be curved or it may be straight.
Instantaneous velocity can be defined as:
“The instantaneous velocity of the object is the limit or average velocity interval with a change in the time and the velocity reached at zero.”
the instantaneous velocity is the velocity of the moving object at some special or specific point or moment. Instantaneous velocity can be derived when we take the average velocity at a specific time.
The mathematical representation of the instantaneous velocity is written below:
vins = Δt0ΔdΔt
There, vins represented the instantaneous velocity, Δt0represented the average limit of the velocity with time, and reached zero, Δd the rate of change of displacement, and Δt represented the rate of change in time.
The formula of the instantaneous velocity can also be written as:
s = v dt
There, s represented the displacement function, v represented the velocity, d represented the displacement of the displaced object and t represented the time in which the body can be displaced.
The SI unit of the instantaneous velocity is the same as the velocity or the average velocity which is a meter per second and is written as ms (ms-1)
Dimension of instantaneous velocity SI unit is written below:
ms-1 = LT-1
There, L is the dimension for m and T-1 is dimension or s-1.
The direction of the instantaneous velocity of the displaced object is always in the direction of the displacement.
The instantaneous velocity of the moving body can't equal zero but the average velocity of the moving body or the object may be equal to zero.
Uniform velocity can be defined as:
“The body that can cover the displacement is equal to the time intervals and moves constantly without changing the displacement in unit time.”
The body can be moved with a uniform velocity when it can cover the displacement, the displacement is equal to the time interval and they are constantly moved.
Non-uniform velocity can be defined as:
"The body that can cover the unequal displacement is equal to the time intervals and moves constantly with changing the displacement in unit time."
Some other units of velocity rather than meters per second are mph or fts-1These two units are also commonly used.
Many different particles can be moved or displaced at the same time with uniform velocity in many different special cases but in these cases, the particles moved with uniform velocity with different time intervals such as v1t1, v2t2, ………. vntn. then we can find the average velocity by using the given formula.
v = v1t1 + v2t2 + v3t3 +v4t4........... + vntnt1 + t2 + t3 +t4........ + tn
Then, we know that t1+ t2 + t3+ …… + tn = t
Now we use the arithmetic mean for the average speed and write as:
v =v1 + v2+ v3 +v4........... + vnn
Also written as:
v = 1n i=1nvi
But when the particles can be displaced with different or numerous distances with equal intervals of time and also with the same distance then it can be written as:
v = s1+ s2 + s3 + s4...... snt1 + t2 + t3 +t4........ + tn
It can also be written as:
v = s1+ s2 + s3 + s4...... sns1v1 + s2v2 + s3v3 + s4v4+ ......+ snvn
In the average speed, we can use the arithmetic mean but when the particles cover different distances then it can be equal to the harmonic mean and it can be written as:
v = n (1v1 + 1v2 + 1v3 + 1v4 + ……. + 1vn)-1
And then according to harmonic mean, it can be written as:
v = n (i=1n1vi)-1
Some different quantities which can be depended upon the velocity are given there:
Drag force
Momentum
Escape velocity
Kinetic energy
Lorentz factor
Their description is given there:
Drag forces are the fundamental concept to understand for understanding the motion of fluid or in fluid dynamics because drag force is the specific force that can act opposite to the object's motion because the body or object can be moved in the fluid so this force helps to move in the fluid in the right direction. The formula for drag force is vine there:
FD = 12 ρ v2 CDA
According to the given formula, it can be shown that the drag force is dependent upon the square of the velocity.
There,
FD represented the drag force in fluid dynamics.
Ρ represented the momentum of the moving object.
v2 is the square of the velocity.
CD is the coefficient of the drag force.
A represents the area in which the drag force or the body can be moved.
The momentum of the body can also depend upon the velocity directly because according to the second law of Newton, the momentum of the body or object is equal to the product of mass and velocity and it can be written as:
ρ = mv
There,
ρ represented the momentum
M represents the mass of the object or body
v represented the velocity of the object through which it can be moved or displaced.
Simply, escape velocity is the velocity of an object to escape from the earth moon or other massive bodies. Through the escape velocity, the rockets can reach space. The general formula that can describe the velocity is given there:
ve = 2GMr
There,
ve represented the escape velocity.
G represented that gravitational force and its value are fixed.
M represented the mass of the object or body
r represented the radius of the body from Earth.
The above formula can also be written as:
ve = 2gr
Kinetic energy can also depend upon the velocity directly and the formula that can show this is given there:
Ek = 12 mv2
There,
Ek represented the kinetic energy.
m represented the mass of the object or body
v represented the velocity and kinetic energy was directly dependent upon the square of the velocity.
In the formula of special relativity of the Lorentz factor, the Lorentz factor depends upon the velocity, and the formula is written there:
🇾 = 11- v2c2
There,
γ represented the Lorentz factor.
V represented the velocity on which the Lorentz factor depends.
c is the speed of light.
When the velocity of the object or the moving body occurs in one dimension, then their velocity is always scalar and it can be written as:
v = v - (-w)
When the two objects can be moved in the same direction the equation can be written like this. But if the two objects are not moved or displaced in the same direction and move in opposite directions then it can be written as:
v = v - (+w)
In the equation of motion velocity is the main integral because through the velocity we can understand the motion of the numerous displaced objects when different forces act upon that. The equation of motions in which the velocity relationship is shown is written below in detail.
The first equation of motion
The second equation of motion
Third equation of motion
The formula of the first equation of motion in which the velocity relation can be shown is given there:
v = vi + at
There,
v is the final velocity, vi represents the initial velocity, a represents the acceleration and t represents the time.
The second equation of motion in which the velocity relationship with the equation is shown is written there.
s = xit + 12 at2
There, s represented the displacement of the moving object, xi represented the initial velocity, a represented the acceleration and t represented the time.
The third equation of motion can be used to analyze the objects that can fall from the height or can also be used to analyze those objects or bodies that can be moved on the highway with high velocity or speed.
v2 = xi2 + 2as
There, v represented the velocity, xi represented the initial velocity, a represented the acceleration of the moving object and s represented the displacement.
Somehow the velocity and the speed are the same but their nature is different because speed is the scalar quantity and the velocity is the vector quantity because it can provide both magnitude and direction. the direction of the velocity is along with the displacement and their direction shows the final point or destination of the displaced object while the magnitude of the velocity is always their speed. Due to the vector nature of the velocity we can use different vector algebraic methods to add or subtract the multiples or the complex velocities efficiently. Numerous objects have different velocities that can act on the body at the same time so understanding them is crucial to understanding the fundamental concept of velocity.
The major differences between the speed and the velocity are given there:

Velocity can be calculated easily but its calculation depends upon the dimension in which the velocity occurs. It can also depend upon the cartesian coordinate system which can be used to represent the velocity. if the velocity can lie on one dimension then it can be calculated easily by dividing the total displacement by the total time taken which can be used by the object to change its position. but if the velocity can lie on the cartesian plane with two or three dimensions then to solve their complexity we can use different vector rules for their division. Some calculations of velocity according to dimension with examples are given there:
When the body can be moved in one dimension then the value of velocity may be positive or negative because the negative and positive velocity describe the direction of the moving body in a single dimension on the x-axis. When the velocity can occur in one dimension then for their calculation we can use the given formula:
v =x2- x1t
There, v represented the velocity and x1 , x2 represented the change of the body from the initial point to the final point and t represented the time taken that can be used to change the position. As we know,
△d = x2 – x1
So the formula can slo be written as,
v = Δdt
As we know Δd represents the displacement of an object.
The complex velocity can occur in more than one dimension like in a dynamic field when two or more objects can be moved then it is complex so we can use the vector rules and it can also help to understand the motion of the body crucially. If the body can be moved in two dimensions, it starts its velocity from the point ( x1, y1 ) to the endpoint ( x2, y2 ) in some time. Then to calculate the velocities we can use the given formula which can be written below:
v = (x2- x1) i + (y2 - y1) jt
There, i, j are the unit vectors of the x and y directions in the cartesian coordinate system.
The complex velocity can occur in more than one dimension like in a dynamic field when two or more objects can be moved then it is complex so we can use the vector rules and it can also help to understand the motion of the body crucially. If the body can be moved in three dimensions, then it starts its velocity from the point ( x1, y1, z1 ) to the endpoint ( x2, y2, z2 ) in some time. Then to calculate the velocities we can use the given formula which can be written below:
v = (x2- x1) i + (y2 - y1) j + ( z2- z1) kt
There,i, j and k are the unit vectors of the x and y directions in the cartesian coordinate system.
Example of velocity in one dimension:
Suppose the body or an object can be moved from the initial point with the speed of 3m and reach the end with the speed of 7m in 5s. Then find the velocity when the body is displaced in the right or positive direction.
To find:
v =?
Given:
x1 = 3m
x2 = 7m
t = 5s
Formula:
v =x2- x1t
Solution:
By using the above formula
v =x2- x1t
By putting the values
v = 7 - 35
v = 45
v = +0.8 ms-1
But if it can move to reverse and move negative direction then,
x1 = 7m
x2 = 3m
t = 5s
By using the formula
v =x2- x1t
By putting the values
v = 3 - 75
v = -45
v = – 0.8 ms-1
Example of velocity in two dimensions:
suppose the body or an object can be moved from the initial point with the speed of (3m, 4m) and reach the end with the speed of (7m, 8m) in 4s. Then find the velocity, magnitude, and direction.
To find:
v =?
v = ?
θ = ?
Given:
x1, y1 = 3m, 4m
x2, y2 = 7m, 8m
t = 4s
Formula:
v = (x2- x1) i + (y2 - y1) jt
Solution:
By using the above formula
v = (x2- x1) i + (y2 - y1) jt
Now by putting the values
v = (7- 3) i + (8 - 4) j4
v = 5+44 , v = 1.25 i + 1j ms-1
Magnitude:
Now apply the formula of magnitude
v = (A)2+ (B)2
Putting the values in the formula
v = (1.25)2+ (1)2
v = 1.7 + 1
v = 1.6 ms-1
Direction:
To find the direction we can use the given below formula:
θ = tan-1(BA)
Now by putting the values
θ = tan-1(11.25)
example of velocity in three dimensions:
suppose the body or an object can be moved from the initial point with the speed of (3m, 4m, 6m) and reach the end with the speed of (7m, 8m, 10m) in 4s. Then find the velocity and magnitude.
To find:
v =?
v = ?
Given:
x1, y1, z1 = 3m, 4m, 6m
x2, y2, z2 = 7m, 8m, 10m
t = 4s
Formula:
v = (x2- x1) i + (y2 - y1) j +( z2- z1) k t
Solution:
By using the above formula
v = (x2- x1) i + (y2 - y1) j +( z2- z1) k t
Now by putting the values
v = (7- 3) i + (8 - 4) j + (10-6) k4
v = 5+44 , v = 1.25 i + 1j + 4k ms-1
Magnitude:
Now apply the formula of magnitude
v = (A)2+ (B)2 +(C)2
Putting the values in the formula
v = (1.25)2+ (1)2+ (4)2
v = 1.7 + 1+ 16
v = 4.32 ms-1
Velocity is the vector quantity or sometimes it becomes more complex so it can be represented in graphic form. The graphic representation of velocity is given there:
Velocity time graph
Position time graph
In the velocity time graph, the whole area which is under the graph represents the displacement that can be covered by the moving object or body or the slope in the velocity time graph represents the acceleration of the moving object.
In the position-time graph of the velocity the straight curve represents that the velocities are constant, curved slope represents that the velocities are not constant but if the slope suddenly becomes curved then it indicates that the velocities are instantaneous. and all of these velocities with their graph are drawn below.
Velocity can play a very fundamental role in different fields like physics, dynamics, and many others some of their applications are given there:
Medicine: in the field of medical sciences, the concept of velocity is used to understand the blood flow or the movement of body parts.
Navigation: velocity helps the pilots and sailors control the speed of the boat and ship.
Engineering: design the new machines after analyzing the velocity.
Sports: velocity helps athlete increase their performance in swimming, running, or other sports activities.
Mostly the complex problems of velocity can be solved by using the given system because they are vectors and vectors are complex and solved by the algebraic methods in some coordinate systems. the higher dimensions problems can be solved in the given coordinate systems.
Cartesian coordinate system
Spherical coordinate system
Polar coordinate system.
In the field of physics, concept of the velocity is crucial to understand because it helps to understand the motion of a moving object efficiently. Velocity can provide the quantity measurement of the moving object, due to its vector nature it can provide both magnitude and direction also.in dynamics or kinematics, velocity helps to understand the behavior of the moving body or object because it can play a very fundamental role in the motion of all bodies or objects. After reading this article the reader can find or understand the velocities that can occur in one direction or dimension or may occur in more than two or three dimensions.
Heat sinks are the electric routes for heat elimination from the PCB body. The digital electronic world is all about making devices compact and more powerful. This is possible only when the printed circuit boards (PCBs) are small enough to fit into the compact device. The increasing demand for power in low space comes with different challenges, of which the most crucial is the heat management of PCBs. The heat sinks are made of elements such as copper, aluminum, diamond, ceramic materials, graphite, etc., and play a crucial role in the thermal optimization of PCBs for optimal performance and long life. This comprehensive guide is about the basic introduction, heat transfer methods, key parameters, design considerations, and manufacturing techniques involved in the heat sink from the PCB point of view.

Heat sinks are the essential components in printed circuit boards that dissipate excess heat from the board and help with thermal management. The electronic components on the PCBs eliminate a lot of heat during their performance, based on the type of PCB and its duty time. Proper heat management is crucial for PCBs to ensure they work in safe temperature ranges and provides the best performance even when working for hours. The following are the basic parts of heat sinks:
It is made of high-conductive material to absorb more heat and eliminate it through the fins and also provide a solid foundation for the whole heat sink.
These are extended plates from the base plate, and the whole heat sink is identified through it. The common heat sink types are straight, louvered, and pin, and the density of the fins determines the thermal dissipation rate.
It is a layer of a specific material placed between the heat sink and PCB to improve thermal contact.
The agency through which the heat is transferred to the external environment is called the cooling medium, and the most common examples are air or fluid.
This is the attachment method of heat sink to PCB and include the fastener or adhesives.
The smaller size and high demand for performance from the PCBs have made the manufacturers think more seriously about dissipating the excess heat, and this has enhanced the value of heat sinks. Heat sinks are engineered near the critical components to draw the heat away, disperse it into the surrounding environment, and prevent overheating for optimal performance.
It is essential to learn the core heat transfer objectives to understand the types, basic principles, and other related information about heat sinks. Heat transfer occurs through three basic phenomena, and let’s discuss each of them from the PCB point of view:
Conduction is the phenomenon of heat transfer from one object to another through direct contact because of the temperature difference between them. In PCBs, conduction occurs when the electrical components expel heat and it transfers toward the heat sink. The transfer rate and efficiency of the heat sink depend on the heat sink and PCB material. It is the most uncomplicated and common type of heat transfer.
The optimal place for the heat sink is exactly on the hotspots, and the most common ones are thermal spreaders, integrated circuits, resistors, etc. When the aim is to provide thermal conductivity through conduction, the manufacturer connects the heating component with the heat sink. Moreover, the fins are connected directly to the hotspot for direct heat elimination towards the external environment.
Convection is the heat transfer from one object to another through fluid movement. In PCBs, convection occurs when the air passes through the heat sink, which eliminates the heat by cooling it down. Basically, there are two types of convection:
Natural Convection
Forced Convection
Natural convection occurs without the help of external equipment or power consumption. This process is comparatively slow, and when designing a heat sink for natural convection, these must be carefully oriented so the air can directly flow through the fins and help cool down the whole PCB system.
On the other hand, forced convection requires an external source, such as a power fan, that takes the power but expels all the heat at a higher rate.
Radiation is the process of heat transfer from one point to another through electromagnetic radiation. It is a good source of thermal optimization in PCBs but is a less common method as compared to conduction and convection. It is simply a phenomenon of heat elimination from an object on a PCB, and the rate of heat transfer depends on the material, surface area, and position of the component emitting heat.
The frequent way to make the heat sink more efficient for radiation is to maximize the infrared wavelength. For this, the heatsinks are made of anodized aluminum to make them more efficient with radiation heat and thermal mechanisms. Moreover, the large surface area is another measure for the same purpose. This heat removal process is useful in heavy-duty and high-temperature applications, and the most supporting point about this method is that radiation is the only heat transfer method in vacuum applications.
When measuring the PCB heat sink performance and designing their locations, multiple factors are kept in mind, and here are some general parameters:
Thermal resistance is the critical point when designing the heatsink. It is the material’s ability to resist the heat flow from the body to the environment. Therefore, low heat sink thermal resistance shows better heat dissipation and is preferable. A higher conductivity of the material means lower thermal resistance. Other factors to judge the thermal resistance are the component's geometry, thermal interface material (TIM), mounting pressure, and the amount of air flowing through the heat sink.
It is the ability of the heatsink to conduct the heat, and the unit to measure it is the W/m·K (watts per meter-kelvin). Elements like copper and aluminum have high thermal conductivity and are considered better options for creating heat sinks. Similarly, plastic and other nonmetals have very low conductivity values.
At very high temperatures, the thermal conductivity of the material is affected, and this results in the unexpected behavior of the material. Moreover, the structure and geometry of the heatsink are another factor affecting the thermal conductivity.
The fin design is another critical point to consider when measuring the heat sink performance of the PCB. The shape, size, position, and spacing influence the thermal management through the heat sink.

In addition to these, the heatsink surface area, position, and airflow are important factors to consider for the PCB heatsink performance.
Several considerations are adopted for the expected performance while designing the heatsinks for the right thermal optimization on PCBs. Here are some of these:
This is the most basic and obvious point that designers have to keep in mind while designing the heat sink for PCBs. Every design is different in surface area, size, and airflow; therefore, the manufacturers have multiple choices according to the PCB type. Some popular heat sink designs are cross-cut, straight fin, and pin fin, and the choice of a particular design depends on the heat dissipation requirements, available airflow, and total space for the heat sink formation.
These are the crucial gateways for the heat elimination of electronic components from the environment. They help to fill the gaps between the components and make the thermal optimization smooth. Some general TIMs are thermal grease and thermal pads, phase change materials (PCMs), thermal tapes, etc., and the right choice of TIM is the key to better heat elimination from PCBs. As a result, the thermal resistance decreases, and more heat dissipates into the surrounding area.
The main heat elimination methods for heat sinks are convection and conduction, and these depend on the perfect contact of the heat sink with the PCB surface. This connection is accomplished using different types of mechanical fasteners, and some common examples are:
Screws
Clamps
Press fit
Clip ons
Adhesive-based attachments
While choosing the right attachment method for a heat sink, always consider parameters such as mechanical stress, compatibility, ease of assembly, etc.
Now let’s discuss the fundamental techniques for crafting the heat sinks in the PCBs for the best thermal optimization.
This manufacturing technique is applied to create the customized heat sink for the PCBs. Here, the heat sink material is usually heated aluminum or copper that is forced through the die to create long-shaped heatsinks with a good cross-section area. The resultant material is then cut into the desired size. The pluses of this technique are precision, efficiency, consistency, and customization according to the manufacturer’s choice. It is usually preferred for LED lights, consumer electronics, and commonly used appliances.
Die casting is the method in which the molten metal is injected into a mold under high pressure to shape the metal according to the PCB’s requirements. This is preferred where complex heat sink shapes are expected to create highly intricate designs and details. Moreover, this is a perfect option for high-volume production in less time.
It is a traditional way to get the right heat sink shape through the localized compressed force of a hammer or die, and the heat sink formed as a result has great mechanical strength. The parts made have high mechanical strength and thermal resistance. This technique is applied to create heat sinks for the PCB, which is expected to be utilized in high-performance fields such as aerospace or military.
This method involves the formation of a heat sink by cutting the flat metal sheets. The metal is sliced and bent according to the size, area, and shape of the heat sink required. It is a comparatively complicated method and is applied to create a high-density fin structure so that thermal dissipation occurs at a high rate. This method is applied to high-duty electronic components such as GPUs, CPUs, etc.
This is a relatively straightforward technique for heat sinks that involves fin attachment to the base through thermal adhesion or solder. The manufacturers have the independence to use different material types and customize them according to the PCB type and thermal requirements. The flexible design results in better performance and reliability.
Hence, this was your guide for the PCB heat sinks, and I hope you got all the information about the topic for what you were searching for. If you want more information, you can ask in the comment section.
Hi friends, I hope you are well and doing good in your fields. Today we can discuss the main topic of displacement which plays a fundamental role in the motion of the object. In simple words to study and understand the motion of objects, the concept of displacement is fundamental. When the object can moved it can change its position and cover some distance and displacement. Both quantities represented the quantitative information or description of the motion of an object. Sometimes both quantities of distance and displacement are understood the same but they are not similar to each other because in distance we can describe the motion of an object as the object can be moved from one position to another position but in displacement we can measure the distance with time.
To understand the displacement it is compulsory to also understand the concept of the position of the object and the distance because after understanding both all these quantities we can efficiently understand the motion of the object in quantitative form.in different fields of physics like dynamics and kinematics displacement concepts are fundamental. Now in this article, we can also discuss the difference between distance and displacement but mainly we can explore the definition of displacement, its mathematical expression, significance, and examples.
Displacement provides a quantitative description of the distance of the object that can covered by the object from its initial position to the final position. Simply we can define displacement as:
"The object that can be moved and change its position from its initial position to the final position is known as displacement."
Displacement provides information about the direction of the object and also provides information on how far the object can be displaced.
Displacement is a vector quantity so that's why it can provide both magnitude and the direction of the object which are in motion.
The displacement can be represented through an arrow or also in bold letters because they are the vector quantity. For example d or as d.
Mathematical expression and formula of displacement are given there:
d = rf - ri
It can also be written as:
d = B - A
B and A represented the initial and the final position.
Or also as;
Δx = xf - xi
Their Δx represented the change in displacement and xf and xi represented the final and initial position of the moving object.
There,
d = represented the displacement in which the object can change the position from the initial to the final position.
rf= represented the final position in which the object can be displaced.
ri = represented the initial position in which the object can be displaced.
The SI unit of the displacement is the meter. And it can be represented as m.
The magnitude of the displaced object is always equal to the length of the line in which the object covers the distance from the initial position to the final position.
Some examples of displacement are given there:
Let us consider the teacher who can take the lecture and use the whiteboard the initial point is when the teacher starts writing and the final point is when the teacher stops writing then the initial point value and the final point value can be subtracted and provide the displacement.
The concept of the position of the object is compulsory to understand because it is the base or fundamental concept in the motion of the object. Even distance and displacement can be described after understanding or knowing the position of the object accurately. In the field of physics, we can discuss motion in kinematics, dynamics, and many others so it is a must to clear the concept of position.
In simple words, the position of the object is the place or area in which the object can moved or placed. In the motion of an object when the object starts its distance or work then it is referred to as the initial point or position or when the object stops moving or stops working then it can be referred to as the final point or position.
For instance, the teacher can take the lecture and use the whiteboard the initial point or position is when the teacher starts writing and the final point or position is when the teacher stops writing then the initial point value and the final point value can be subtracted and provide the displacement. Like this, every object that can be moved has some starting position where it can be placed and some final point where it stops. everything has different positions in which they are placed but in physics to understand motion, displacement, distance, and velocity it is fundamental to clear the concept of position also.
After understanding the position of the object now we discuss the main topic of distance, many people are confused or assume that both distance and displacement are the same but they are not the same they are different from each other. In simple words, distance are movement of the moving object from one point to another point and it can describe the direction also but displacement provides the both direction and magnitude of the moving object.
In the given figure the distance and displacement are both shown. The body that can start its journey from its starting point and end its some final point the whole path that can be covered by the body or the longest path that can be covered by the body or moving object is termed as the distance but the displacement is the shortest distance which can be covered by the moving body or an object.
The major differences between the distance and the displacement are given there:

To find:
Displacement = Δx = d = ?
Formula:
The formula that can be used to find the displacement is:
Δx = xf - xi
Given:
xi= 0
xf = 150 m – 205 m
Solution:
Δx = xf - xi
By putting the values of the final and initial position of the object
Δx = (150 m – 205 m) - 0
The four different objects can be moved and have different initial points and final points and they are opposite to each other as shown in the given figure below there:

The four objects that are moved in the tiles are the different initial and final point values. The tiles' sides square are equal to 0.7 km. By understanding the given figure calculate the distance that can covered by all four objects and also calculate the magnitude of displacement of all 5 different objects.
To find:
The total distance that can be covered by the 5 objects = D =?
Given:
AB = 4.2
BC = 1.4
CD = 2.1
DE = 0.7
EF = 0.7
Formula:
The formula which can be used to calculate the total distance is given there

D = 9.1 km
We can calculate the magnitude of the displaced objects by using the Pythagorean formula which is given there:
AF2 = AH2 + HF2
According to the given figure,
AH = 2.8
HF = 2.1
Now by using the formula,
AF2 = AH2 + HF2
Putting the values then we get
AF2 = ( 0.7 4)2 + ( 0.7 3)2
AF2 = (2.8) 2 + ( 2.1)2
AF2 = 7.84 + 4.41
AF2 = 12.25
Now taking square root on both sides
AF2 = 12.25
Then,
AF = 3.5 km
Example no 4:

Formula:
Δx = xf - xi
Solution:
By putting the values in the formula
Δx = xf - xi
Δx = 9.5 - 0
Δx = + 9.5
Now we can also explore the nature of displacement its significance, graphical representation, their application in real life.
All vector quantities provide both magnitude and direction. So the displacement which also has a vector nature provides both magnitude and direction. In displacement the magnitude is equal to the straight path or line that is present between the two points starting or ending and the whole path is covered by the moving object. the direction of the displaced object is the line or path that starts from the initial or ends to the final point. By using the algebraic method or formulas for adding, subtracting, or multiplying rules we can also perform these operations on displacement. Simply we can add or subtract the displacement according to the vector's algebraic rules or methods. Vector adding is complex but we can do many other mathematical operations by using different methods or by following the vectors rules efficiently.
The displacement of the displaced objects can be calculated but it can depend upon their rectangular coordinate system or on the dimensions in which it can lie. Because to can use the simple displacement formula when we can calculate the displacement of displaced objects that can be lied on one dimension. But when we want to calculate the displacement of those displaced objects which can be lied on two or three dimensions we can use the vector rule or method for their subtraction. the formula which can be used to calculate the displacement are given there.
Displacement in one dimension:
The object can be moved in one direction or one dimension, Displacement is the distance that can be covered from the initial and the final point and it can easily calculated by subtracting the final value point from the initial value point. Their formula or equation is represented as:
d = xf – xi
Displacement in two dimensions:
The object can be displaced in two dimensions, Displacement is the distance that can be covered from the initial ( x1, y1) and the final point (x2, y2) along the axis or dimension of x and y. Their formula or equation is represented as:
d = ( x2 - x1) i + ( y2- y1) j
there,
i represented the unit vector on the x-dimension.
And,
j represented the unit vector on the y-dimension.
Displacement in three dimensions:
The object can be displaced in two dimensions, Displacement is the distance that can be covered from the initial ( x1, y1) and the final point (x2, y2) or the ( z1, z2) along the axis or dimension of x, y, and z. Their formula or equation is represented as:
d = ( x2 - x1) i + ( y2- y1) j + ( z2 - z1) k
there,
i represented the unit vector on the x-dimension.
j represented the unit vector on the y-dimension.
and,
k represented the unit vector on the z dimension.
Now the detailed discussion about the displacement in one dimension or two or more dimensions is given there:
When the object can be displaced in one dimension then there displacement is in a straight line so that's why the displacement value may be positive or negative because its direction can slo indicating the straight line motion in one dimension with a single axis x.
Let us consider whether the object can be displaced from the starting point or the initial point value is 4 m and the final or ending point value is 6 m then we can calculate the displacement by using the formula and they are given there:
d = xf – xi
By putting values
d = 6 m - 4 m
d = + 2 m
But if the object can move backward then the displacement value is negative then their initial value is 6 and the final value is 4 then it can be written as;
d = 4 m - 6 m
d = – 2 m
The displacement value is negative.
When the displacement lies in two or three dimensions then it can be represented in the form of a vector because in higher dimensions it is complex to represent the displacement in simple form so that's why it can be represented in multiple axes with vectors. These methods are mostly used to deal with the complex paths in which the objects are displaced.
Example of displaced objects in two dimensions:
The objects that are moving in the path have the starting point A, their initial point values are ( 2, 4) and the ending point values B are ( 3, 8) now find their displacement, magnitude, and direction also.
To find:
Displacement = d = ?
magnitude = d = ?
Direction = θ =?
Given:
x1, y1 = 2, 4
x2, y2 = 3, 8
Formula:
For displacement:
d = ( x2 - x1) i + ( y2- y1) j
For magnitude:
d = A2+ B2
For direction:
θ = tan-1(BA)
Solution:
Firstly we find the displacement by using the formula of displacement.
d = ( x2 - x1) i + ( y2- y1) j
By putting the values
d = ( 3 - 2 ) i + (8 - 4) j
d = 1 i + 4 j
Now use the formula of magnitude:
d = A2+ B2
By putting the values
d = 12 + 42
d = 1 + 16
d = 4.1
Now use the formula of direction:
θ = tan-1(BA)
By putting values
θ = tan-1(41)
Example of displaced objects in three dimensions:
The objects that are moving in the path have the starting point A, their initial point values are ( 2, 4, 2) and the ending point values B are ( 3, 8, 7) now find their displacement and magnitude.
To find:
Displacement = d = ?
magnitude = d = ?
Given:
x1, y1 = 2, 4
x2, y2 = 3, 8
z1 , z2 = 2, 7
Formula:
For displacement:
d = ( x2 - x1) i + ( y2- y1) j
For magnitude:
d = A2+ B2
Solution:
Firstly we find the displacement by using the formula of displacement.
d = ( x2 - x1) i + ( y2- y1) j + ( z2 - z1) k
By putting the values
d = ( 3 - 2 ) i + (8 - 4) j + (7 - 2 ) k
d = 1 i + 4 j + 5 k
Now use the formula of magnitude:
d = A2+ B2+ C2
By putting the values
d = 12 + 42 + 52
d = 1 + 16 + 25
d = 42
d = 6.5
For understanding the fundamental concept of relative motion, displacement concepts are basic. because in relative motion the displacement of the one-displaced object is assumed to the other relative motion. When the two objects are displaced or in continuous motion, then the displacement of one displaced object is relative to the other displaced object and they have the vector difference according to their displacement values.
For example:
Let us consider the two objects A and B are displaced at the path, their starting moving point values or the ending point values of object A are ( 2, 4) to ( 6, 8) and the starting and the ending point values for the object B are ( 0, 0 ) to (1, 4). They find the displacement of the object A relative to the object B.
To find:
drel = ?
d A = ?
d B = ?
Given:
A = (2, 4) (6, 8)
B = (0, 0 ) (1,4)
formula :
d A = xf – xi
d B = xf – xi
drel = d A – d B
Solution:
Firstly find the d A by using the formula
d A = xf – xi
By putting values
d A = (6-2) - (8-4)
d A= 4i + 8j
Then find the d B by using the formula
d B = xf – xi
d B = ( 1 -0 ) + ( 4 -0 )
d B = 1i + 4j
Then find the relative displacement by using the formula
drel = d A – d B
Now by putting the values
drel = (4i + 8j) - ( 1i + 4j)
drel = 3 i + 4j
Displacement can slo be represented in the form of a graph because they are vectors so that's why the vectors are complex and efficiently represented on the graphs.
In the graphical representation, the displacement is represented by putting the arrow on their starting or ending points. In the graphics; the representation of the displacement the slope represents the velocity of the displaced object.
In the given graphical representation of the displacement the straight line represents the positive velocity that is constant and does not change with time but in the next graphical representation, the curve represents that the velocity changes with time and they are not constant.
The graphical representation can be changed when the displaced object's starting or final values are different with different velocities this graph representation depends upon the velocity and the starting or ending point values of displaced values.

Hello readers! Welcome to the easiest explanation of the current divider circuit. I hope you are doing well. In electrical and electronic circuits, the current distribution among different components and branches is the fundamental concept and it must be crystal clear in mind to understand the circuit working. One key concept that helps to understand this flow is the current divider rule, which is purely related to the parallel circuits. It is the method of determining electrical current flow into multiple paths of the parallel connection circuit.
Today, we’ll shed light on the basic introduction of the current divider and the discussion will start from scratch. You’ll see the basic concepts of the circuits, working, derivation, and applications of the current divider in the circuit. Moreover, some practical examples will be provided here for clear concepts and the learning of real-time problem solutions using current divider equations. I hope you’ll find all the required information here so let’s get started.
The current divider circuit refers to the circuit configuration in which the current flowing through the current source is divided into multiple parallel paths and each of them has its resistance or impedance. The amount of current flowing through each branch is determined through its resistance value. The basic principle of the current divider circuit follows Kirchoff’s current law and Ohm’s law; therefore, the derivation of the current divider also follows the mathematical representation of these two.
In simple words, the current divider enables one to determine the fraction of the total current flowing through each branch of the circuit. This becomes particularly useful in parallel circuits where the paths have different resistance values so the current is not the same across each branch.
Before working on any circuit, one must understand the basic concept related to the topic. Here, for the current divider, it is important to understand some fundamental terms and their explanation. Even if you already know these, you have to revise them because these will be utilized in the current divider derivation.
Parallel circuits are those where multiple components are connected by sharing the same two nodes. In this way, they all share the same current source, and the current flowing through each of them is divided among these components. Always remember that the voltage across each component in the parallel circuit is the same.
The resistance of the electrical component refers to the opposition of the current flowing through the component. It varies from component to component and plays a crucial role in the current divider rule. It is indicated by the symbol “R” and is mathematically represented as:
R=1/I
Where I is the current flowing the component.
The equivalent resistance of the parallel circuit is the total resistance of the circuit or a particular combination of the components. It is represented as the Req and is the sum of the resistance of every component under consideration. If a circuit has the N number of components, then the equivalent resistance of the circuit is represented as:
Req=I/R1+1/R2+1/R3+......+1/Rn
Ohm’s law is the fundamental law in electrical engineering, and it involves the representation of the voltage, current, and resistance of the circuit. This law states that:
“The voltage across the conductor is directly proportional to the product of resistance and current of a component, provided the temperature and other physical conditions remain the same.”
The mathematical expression for the above statement is given below:
V=IR …………….. (1)
Where,
V= Voltage of the conductor
I= Current flowing through the conductor
R= Resistance offered by the conductor
Kirchoff’s current law is another fundamental concept in the electrical circuit that states that:
"The sum of all the currents entering the particular node is equal to the sum of all the currents leaving the node."
In simple words, the algebraic sum of all the current entering the node and flowing out of it is always zero. The mathematical representation of this rule is given here:
∑Iin = ∑Iout ……….(2)
Here,
∑Iin= Sum of all the current entering the node
∑Iout= Sum of all the currents leaving the node
In other words, the total current passing through the circuit is equal to the sum of all the currents passing through each component of the circuit.
IT=I1+I2+I3+.......+In …..(3)
The core principle of the current divider rule is based on Ohm's law and Kirchoff’s current law. These two, when combined, can be applied to solve the intricate circuit with multiple nodes and paths. Let’s rearrange Ohm’s law and derive the current divider equations. In the parallel circuits, the voltage across each component is the same. Hence, use equation 1:
V=InRn
Rearranging the above equation gives us the following:
In=V/Rn ……….. (4)
Let's say we have a parallel circuit with the two resistors R1 and R2. Ohm’s equations in this case are:
I1=V/R1 for R1 ……….. (5)
I2=V/R2 for R2 ……….. (6)
Applying Kirchoff’s current law here, utilizing equation 4:
IT=I1+I2
IT=V/R1+V/R2
IT=V(1/R1+1/R2)
IT=V(R2+R1/R1R2) …………. (7)
For the potential difference in a circuit, the above equation becomes:
V=IT x (R1R2/R2+R1) ……….. (8)
Substituting the values of V in Equation 5
I1=IT x (R1R2/R2+R1) /R1 ………… (9)
Similarly, utilizing equation 6 for I2
I2=IT x (R1R2/R2+R1)/R2 ………. (10)
Generally, to find the current in the single node, the equation can be rearranged as:
In=Itotal(Rtotal/Rn) ……….. (11)
Where n denotes any path number.
As a result, the current divider equations can be applied to find the total current of the circuit or to calculate the individual current from any branch.
Let's explore some practical applications of current divider equations through a series of simple circuit examples. For this, we’ll be employing the above-derived equations.
The following is a parallel circuit with three branches; each branch contains a bulb that acts as a resistor. The resistance in these bulbs is denoted as R1, R2, and R3. The resistance values are 10 ohm, 12 ohm, and 13 ohm, respectively and the voltage of the source is 12V. Apply the current divider rule and find the current flowing through each branch.
Given data:
R1=10Ω
R2=12 Ω
R3=13 Ω
V=12 V
To find the equivalent resistance, apply the formula:
1/Req=I/R1+1/R2+1/R3
1/Req=I/20+1/12+1/13
1/Req=0.1+0.0833+0.0769=0.2602
Taking the reciprocal
Req=1/0.2602
Req≈3.844Ω
To find the total current of the circuit, apply Ohm’s law
IT=V/RT
IT=12/3.844
IT=3.14A
Now, utilizing equation 11 for individual currents
In=Ieq(RTl/Rn)
For I1
I1=IT(Req/R1)
I1=3.14(3.844/10)
I1≈1.2A
For I2
I2=IT(Req/R2)
I2=3.14(3.844/12)
I2≈1.0A
For I3
I3=IT(Req/R3)
I3=3.14(3.844/13)
I3≈0.923A
To verify our results, let's sum up all the currents using equation 3 to see if these are equal to the total current or not.
IT=I1+I2+I3
IT=1.2+1.0+0.923
IT≈3.1.4
The results are approximately identical.
The given circuit represents a parallel configuration with three resistive branches powered by a 12V source. The resistors, R = 6 k ohm, R=4k ohms, and R3 = 2 k ohm, share the same voltage. Find the tidal current flowing through the circuit and the current passing through each node separately using the current divider rule.
Given data:
R1=6kΩ
R2=4k Ω
R3=2k Ω
V=12 V
Let’s figure out the equivalent resistance of the circuit using the equation
1/Req=I/R1+1/R2+1/R3
1/Req=I/6000+1/4000+1/2000
1/Req=0.000167+0.00025+0.0005=0.000917
Taking the inverse of the above values
Req=1/0.000917
Req≈1091Ω
To find the total current of the circuit, apply Ohm’s law
IT=V/RT
IT=12/1091
IT≈11.00mA
Now, let’s use the equation 11
In=Ieq(RTl/Rn)
For I1
I1=IT(Req/6000)
I1=11(1.91/6000)
I1≈2mA
For I2
I2=IT(Req/R2)
I2=11(1.91/4000)
I2≈3mA
For I3
I3=IT(Req/R3)
I3=11(1.91/3000)
I3≈5.50mA
Let’s sum up all the currents to verify the results
IT=I1+I2+I3
IT=2mA+3mA+5.50mA
IT≈11mA
The current divider rule has a fundamental role in the current and parallel circuit analysis in electrical and electronic circuits. The following section provides information about the basic electrical applications and the use of current divider equations to find the missing values. This not only provides the right information about the circuit but helps to maintain the component’s lives.
The transistor always works on a specific range of currents and voltages; therefore, maintaining the right current values is crucial. The current divider is applied to provide the important biasing current to the base of the gate terminal of a transistor for optimal performance. This is especially critical when an application has hundreds of thousands of transistors of the same kind working together.
In power distribution systems, optimal load sharing is important to maintain the system’s performance and the component’s integrity. This is done by carefully applying the right load to each component and the current divider rule and equations are useful to calculate the right load on multiple branches.
For instance, in the parallel battery connection, the right load must be applied to each battery according to its capacity. The current divider rule ensures that each battery shares the right load enhancing its efficiency and longevity.
The current dividers help in the circuit to regulate the working for a specific limit. The resistance values of the component are perfectly set so no component gets more current than its tolerance values. The appropriate resistance values ensure the safety and performance of the particular component.
In telecommunication, a particular amount of single transmission is crucial, and one way to manage the signal distribution is to employ the current divider circuit. It helps in the right division of the signal among different pathways and to optimize the network’s performance.
In addition to this, the current dividers are applied for the right impedance matching so all the signals can be distributed to the right component.
In some circuits, only a fraction of the current is converted into voltage and this calculation must be accurate. This is done using the current divider calculations by selecting the right resistance values. As a result, the exact values of the current output can be gained that are directly proportional to the input voltage values.
The current divider is applied to multiple types of circuits ranging from simple to complex ones. For instance, in the light connection circuits, the current dividers are used to control the bulb brightness through the current limitations. It ensures that every bulb is getting the right amount of current and it can vary according to the total current applied to the whole circuit.
Similarly, these circuits are applied to the audio system to control the volume of the speaker or other output devices.
The applications of the current divider do not end here, but now you may have an idea about its working, applications, examples, and importance through this article. It is a fundamental concept in the circuit analysis that is employed to solve the intricate circuits. I hope this was a useful study for you. If you want to lean more, you can ask in the comment section.
Hi readers, I hope you are all well. In this post, we discuss the main topic, equilibrium. Equilibrium can play a fundamental role in the modern and different fields of science. In physics, engineering, or also in chemistry the concept of equilibrium describes and provides information about forces that can be applied to the system. In physics, the equilibrium describes the balanced forces and the torque that can be acted on the system or the body. if the body is at rest or in a motion state, equilibrium explains and provides information about the forces that can act in both types of situations persons.
Equilibrium plays a vital role in understanding the forces and the torque because equilibrium provides stability to the system, also it stabilizes the person who is in the state of rest or motion because in both conditions forces always act on it, so for their stabilization equilibrium plays an essential role.
In this post, we can discuss the equilibrium definitions, their types, first equilibrium condition, second equilibrium condition, mathematical expressions, their applications, examples, and related phenomena.
Equilibrium can be defined as:
"The state in which the body is in the state of balance, or the body is in the state of motion or rest with uniform velocity and no net change occurs on it."
Simply equilibrium is a state in which the system or the body is at the condition of balance under the action of forces but there is no net change occurring. Every system achieves equilibrium at some conditions because, without an equilibrium state, the system or the object can't do its work properly.
There are two main types of equilibrium which are common and they are given there:
Mechanical equilibrium
Thermal equilibrium
Their description is given there:
Mechanical equilibrium is the main type of equilibrium and it can be defined as:
In the system or an object mechanical equilibrium occurs when there is no force, torque net force, or acceleration acting on the object or the system.
Mechanical equilibrium occurs during the state of motion mostly. Mechanical equilibrium can be divided into two types which are also the main types of equilibrium and they are given below:
Static equilibrium
Dynamic equilibrium
These are the further divisions of the mechanical equilibrium Details are given there:
Static equilibrium can be defined as:
"static equilibrium can achieved by the body when the body is at rest and all forces which can act on the body including torque and acceleration sum is equal to zero."
Dynamic equilibrium can be defined as:
"Dynamic equilibrium can be achieved by the body when the body moves with a constant velocity and the all forces and torque which can be acted on the body their sum is equal to zero.”
Thermal equilibrium can be defined as:
"The two objects or the two or more systems can achieve the state of thermal dynamics when no exothermic or endothermic heat exchange occurs and with some condition or time both systems can be reached to the same temperature."
These are the major types of equilibrium but the types of equilibrium in physics are given there:
The types of equilibrium in physics with their uses and examples are given there:
Dynamic equilibrium
Radiative equilibrium
Thermal equilibrium
Static equilibrium
Chemical equilibrium
Their detailed definitions, mathematical expressions, formulas, and examples are given there:
Dynamic equilibrium can be achieved by the body when the body moves with a constant velocity and all forces and torque which can be acted on the body their sum are equal to zero. In dynamic equilibrium all forces which can be acted on the object are balanced. Mostly dynamic equilibrium can be used to understand or determine the objects that can be moved without acceleration.
As we know in dynamic equilibrium the all forces sum is equal to 0 then it can be written as:
F = 0
Or the sum of torque is also equal to zero, hence it can be written as:
𝛕 = 0
The body or object can be rotated around its axis with uniform angular velocity and no acceleration can be calculated or measured and all sum of forces that can be acted are 0
The car that can be moved with uniform linear velocity on a straight road, and not change their speed then the force which can be acted to maintain the road friction or air friction can be produced through the driving force which can be produced through the engines.
The paratrooper can also fly in the sky due to the dynamic equilibrium which stabilizes them to fly in the sky efficiently.
The airplane can also fly with a state of dynamic equilibrium because it can fly with constant speed and the weight and thrust force can balance the drag force by balancing their forces it can fly efficiently.
Radiative equilibrium is the state that can be achieved by the system or the object by absorbing the radiation or emitting the radiation at the same time and rate through equal emitting and absorbing radiation of the system and the object can achieved the dynamic equilibrium state efficently.
Rate of absorption of radiation = rate of emission of radiation
Stars can also maintain their lifecycle phase by emitting or absorbing radiation and achieving radioactive equilibrium. the stars produce energy through the nuclear fusion reaction and it can also radiate the absorbing energy into space and maintain gain radiative equilibrium.
The temperature or radiation can come from the sun and is maintained in the earth by radiative equilibrium because the earth absorbs all solar radiation and emits infrared radiation on the surface of the earth.
The two objects or two or more systems can achieve the state of thermal dynamics when no exothermic or endothermic heat exchange occurs and with some condition or time, both systems can reach the same temperature. thermal equilibrium concepts are essential in thermodynamics and also in their laws.
The temperature of the object and the system that can achieve the thermal equilibrium can represented through the symbol T.
No heat exchange occurs in the system when they achieve the thermal equilibrium then it can be written as:
T1 = T2 = T3=........ = Tn
For the two metal spoons, one is cold or the other is hot but if we check after some time then it can be observed that both metal spoons have the same temperature because both of them achieve thermal equilibrium.
If we leave the hot cup of tea or coffee in the room or open environment, then after some time we can observe that the hot cup of tea or coffee temperature becomes equal to the room or environment temperature,
Static equilibrium can achieved by the body when the body is at rest and all forces that can act on the body including torque and acceleration sum are equal to zero. In the static equilibrium state, the object always remains at rest so that's why the static equilibrium can be used to determine or understand those objects that can't move and always remain at rest. Simply static means rest so static equilibrium can only achieved by those objects or systems that can't be moved.
As we know in static equilibrium the all forces sum is equal to 0 then it can be written as:
F = 0
F represents the sum of all forces that can be acted on the body or object.
Or the sum of torque is also equal to zero, hence it can be written as:
𝛕 = 0
𝛕 represents the sum of all torques that can be acted on the body or object.
The book can be lying on the table or at rest, then the forces that can be acted on the table are maintained or normalized through the gravitational force that can be acted on the book which is lying on the table
The bridge that can be used for traffic is always in a static state, then it can maintain its static equilibrium by balancing the forces and the weight or load that act on the bridge.
In chemical reactions, chemical equilibrium can be achieved, when the forward and the reverse reaction rates are the same under the same conditions, and when the concentration of the products and the reactants can't be changed during the reaction then this state can be achieved. Mostly in chemistry, the chemical equilibrium can be used to determine or understand the concentration of reaction but in physics sometimes it can be used.
The rate of forward reaction = the rate of reverse reaction
The solution of the salt becomes in the equilibrium or saturation state when the rate of salt dissolution is equal to the rate of precipitation. But if we can provide the temperature to the solution of salt then we can change their equilibrium state also.
When we close the container in which hydrogen iodide solution is present, then this solution can achieve the equilibrium state easily because, in the closed container, we can't change the conditions and can't change the temperature or concentration of the reactant and product amount.
Two main conditions are essential for achieving the equilibrium state. If the object and the system can't follow these two main conditions then it can't achieve the equilibrium state. The two conditions for the equilibrium state are given there:
The first condition of equilibrium ( equilibrium of forces)
A second condition of equilibrium ( equilibrium of torque
in the previous post, we can discuss the first condition of equilibrium and now we can discuss the detail of the second condition of equilibrium.
The second condition of equilibrium can also referred to as the equilibrium of torque. According to the second condition, the all torque that can be acted on the body, their sum is always equal to zero. If the object or system follows this condition then it means that the body can't rotate around its axis and can't do the rotational motion.
The second condition of equilibrium is defined as:
The sum of all vector torque that can be acted on the object or the system is always equal to zero. Because this condition describes that the object or the system can't do the rotational motion around their axis.
𝛕 = 0
𝛕 represented the sum of all torque that can be acted on the body.
As we know the torque is equal to the position vector or the distance from the axis of rotation and the vector product of force F and the sin θ are the angle between the r and f. The it can be mathematically represented as:
𝛕 = r F sin θ
Then if the sum of all torque is equal to zero it proves that the body which can be moved with rotational motion is at the equilibrium state and all forces have become zero and it can be written as:
𝛕 = 0
When all forces that can be acted on the object in one plane or are coplanar then we can apply the condition of equilibrium we stabilized or maintained them.
All forces can be passed through one point which is the line of action and the body moves around into its axis within the line of action.
By choosing the axis we can calculate the torque efficiently and the position of the object and the position of the axis is arbitrary.
The second condition of equilibrium or the equilibrium of forces is essentially used to determine or understand those systems or objects that can do the rotational motion.
This condition is the base in the field of dynamics because in this field we can deal with different types of motion. In mechanics, it can help to analyze the structures and the components that can be used in the designing of the system which can do the rotational motion, and also analyze how they achieve the equilibrium state by balancing the forces and the load which can be acted on them.
The seesaw can pivot in the center. Two children with different weights sit on both sides but they can show the equilibrium state when the torque that can be acted on is equal to zero by balancing the load or forces that can be acted on the swing.
The ladder can stand with the support of the wall. The ladder may fall but if it becomes at the equilibrium state by balancing the forces then it can't fall.
The second condition of equilibrium can follow many different fields of science and it can be used in many different applications that can be used in daily life some explanations are given there:
Every day situations
Structural engineering
Mechanical system
In our daily lives, the second condition of equilibrium can be used to balance or stabilize many different things. All systems can be managed or stabilized due to equilibrium. For instance, the picture can be hung with the hook and the weight of the picture or sign can be balanced through the hook. Torque can also be produced by the picture and it can be balanced by following the second condition of equilibrium.
In the field of engineering, engineers can design or choose the components that can manage the rotational motion with equilibrium and manage all forces or torque that can be acted on it. Engineers always prefer to choose those components that can efficiently work and remain in the equilibrium state. For instance, the cantilever beam can be designed by the engineers, they calculate the all torque that can be acted on it and then also analyze that they can able to bear the load or ensure that the beam is at an equilibrium state or not move around their axis to produced torque.
The second equilibrium can be used in the field of mechanics in which the components are designed to work properly without error. The second condition of equilibrium can also used for checking the proper functioning of the machines and also for their safety and for increasing their efficacy to do work properly. For instance, the gear systems that are used in the vehicles are designed by the engineers, they can be designed by ensuring the components can balance all forces and the torque must be equal to 0.
With time and with the development of modern science and technology equilibrium can be used in many different new topics with new concepts and ideas that can be presented through modern research. Some modern concepts and ideas about the second condition of the equilibrium are given there:
Equilibrium in the quantum system
Metastable equilibrium
Equilibrium in the dynamic systems
The second condition of the equilibrium can also now be used in the quantum system because in the quantum system the probabilities and managed or stabilized efficiently. The superpositions and the quantum tunneling can also be understood or determined through the second condition of the equilibrium. For instance, the electrons that can distributed in the conductors, the energy, and the distribution of the electrons can be managed or stabilized by using or following the conditions of the equilibrium.
The second condition of equilibrium can be used in the metastable, in this, the larger or smaller distribution can be managed or stabilized efficiently. For instance, the pencils that we can use can also be balanced on the tip, but if a small disturbance occurs the pencil can fall and distribute the equilibrium state easily.
In the dynamic system, the equilibrium occurs when it follows the second condition of the equilibrium. If we understand the equilibrium of torque then we can analyze or stabilize all control systems or dynamic systems. For instance, the satellites can be moved around their axis, and in the orbit, their stabilization can be managed by following the second condition. Because the second condition of the equilibrium maintained to move in orbit or doesn't allow them to move irregularly in the other orbits.
The advanced topics in which the second condition of equilibrium is used are given there:
Equilibrium in elastic system
Equilibrium in the three-dimension
Multiple forces equilibrium in the system
Some practical examples in which the second condition of equilibrium is used are given there:
Aerospace engineering
Architectures
Building designs
Robotics
Automotive engineering
The equilibrium of torque, which is also referred to as the second condition of the equilibrium is the essential or fundamental concept in the dynamics or mechanics in which the system and the object can do the rotational motion. If we can apply the second condition of equilibrium we can stabilize the different applications in daily life or mechanics. In the era of the modern sciences, equilibrium is essential in every system for working properly and for better output efficiency. by understanding this article or post or understanding the second condition of equilibrium it is easy to balance the objects in the physical world and also in the major fields of science.
