Answer

According to the principle of moments, if the algebraic sum of moments of all the forces, acting on the body, about the axis of rotation is zero, the body is in equilibrium. Therefore, as per the principle of moments,

sum of anticlockwise moments = sum of clockwise moments

For example, a physical balance works on the principle of moments.
