What is equilibrium &write its conditions

The conditions for an object to be in equilibrium are:

• The net force acting on the object must be zero. This ensures translational equilibrium, meaning the object is either at rest or moving with constant velocity.

$$\sum \vec{F} = 0$$

• The net torque acting on the object must be zero. This ensures rotational equilibrium, meaning the object is either not rotating or rotating at a constant angular velocity.

$$\sum \vec{\tau} = 0$$
