1.	What are Equilibrium of rigid bodies ? Give the posses of Equilibrium.
Answer» A rigid body is said to be in equilibrium if both the linear momentum and angular momentum of the rigid body remain constant with time. It must posses the following two equilibria simultaneously: (i) Translation equilibrium: The resultant of all the external forces acting on the body must be zero. (ii) Rotational equilibrium: The resultant of all the torques due to all the forces acting on the body about any point must be zero.

Answer»

A rigid body is said to be in equilibrium if both the linear momentum and angular momentum of the rigid body remain constant with time.

It must posses the following two equilibria simultaneously:

(i) Translation equilibrium: The resultant of all the external forces acting on the body must be zero.

(ii) Rotational equilibrium: The resultant of all the torques due to all the forces acting on the body about any point must be zero.
