When the sum of the forces of an object acting on it is equal to zero then the object is said to be transnational equilibrium .. In the other hand , when the sum of an object torques is zero then it is known rotational equilibrium .

In rotational equilibrium, all torques that are acting on an object must be balanced. For example, a torque applied that would spin an object clockwise has to be counteracted by a torque of equal strength that would spin the object counterclockwise. This doesn't necessarily mean all torques acting on the object must be equal to each other, just that each torque needs its equal but opposite force. Although Newton's laws of motion describe the dynamics of linear motion and forces, the same laws govern rotational motion. Torque is the rotational equivalent of force, which causes an object to have rotational acceleration. In addition, torque occurs due to a force applied on a lever arm perpendicular to the axis of rotation. Rotational equilibrium can be seen where there are equal weights on a balanced plane spinning at a fixed speed. whereas An object is said to be in transnational equilibrium when the sum of the forces acting on it is equal to zero.
