Question

Explain different types of equilibrium of a rigid body? ​

Answer 1

Answer:

If the total force on a rigid body is zero then the body shows translational equilibrium as the linear momentum remains unchanged despite the change in time: If the total torque on a rigid body is zero then the body shows rotational equilibrium as the angular momentum does not change with time.

Answer 2

Equilibrium of a Rigid Body

A rigid body is a system of many particles. It is not essential that each of the particles of a rigid body behaves in a similar manner like the other particle. Depending on the type of motion every particle behaves in a specific way. This is where the equilibrium of rigid bodies comes into play. How this equilibrium affects the whole system of particles is what we shall learn now.
