What is meant by equilibrium of a particle class 11?
A particle is said to be in equilibrium when the net external force on it is zero.
How do you find the equilibrium of a particle?
When a particle is in equilibrium, the vector sum of all the forces acting on it must be zero (Σ F = 0 ) . This equation can be written in terms of its x, y and z components.
What is equilibrium in physics class 9?
Equilibrium in physics refers to the condition of the system when neither of its state of motion nor its internal energy state changes with the time. A simple mechanical body is known to be in the state of equilibrium when it experiences neither the linear acceleration nor the angular acceleration.
When a particle is in equilibrium the resultant force is?
For the particle to be in equilibrium, resultant of all forces acting on it should be equal to zero. In mathematical representation this condition is called an equilibrium equation.
What is the principle of equilibrium?
When all the forces that act upon an object are balanced, then the object is said to be in a state of equilibrium. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s. This extends from Newton’s first law of motion.
What are the three conditions of equilibrium?
A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply :
- The lines of action are coplanar (in the same plane)
- The lines of action are convergent (they cross at the same point)
- The vector sum of these forces is equal to the zero vector.
What is difference between couple and moment?
A couple consists of two equal and opposite forces acting with two different but parallel lines of action. Moment of a force is dependent on the distance from the pivot and the magnitude of the force while the moment of a couple is the net effect of the two moments of the forces.
What are the two types of equilibrium in physics?
There are three types of equilibrium: stable, unstable, and neutral.
What are two conditions of equilibrium?
What are Two Conditions for Equilibrium
- The sum or resultant of all external forces acting on the body must be equal to zero.
- The sum or resultant of all external torques from external forces acting on the object must be zero.
What are the general conditions of equilibrium?
For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero.
What is the SI unit of couple?
A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular distance or moment. The simplest kind of couple consists of two equal and opposite forces whose lines of action do not coincide. The SI unit for the torque of the couple is newton metre.
What is an example of equilibrium in physics?
An equilibrium is said to be stable if small, externally induced displacements from that state produce forces that tend to oppose the displacement and return the body or particle to the equilibrium state. Examples include a weight suspended by a spring or a brick lying on a level surface.
What is the definition of equilibrium in physics?
Equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
What is equilibrium vector?
The Vector Equilibrium, as its name describes, is the only geometric form wherein all of the vectors are of equal length. This includes both from its center point out to its circumferential vertices, and the edges (vectors) connecting all of those vertices.
