When both the net external force and the net external torque acting on it are zero.

Vedclass · Answer

(C) body is said to be in mechanical equilibrium if both the net external force and the net external torque acting on it are zero.Mathematically,for mechanical equilibrium:$1$. The vector sum of all external forces must be zero: $\sum \vec{F}_{ext} = 0$.$2$. The vector sum of all external torques about any point must be zero: $\sum \vec{	au}_{ext} = 0$.If these conditions are met,the body will have no linear acceleration and no angular acceleration.
