Question

discuss the condition of rotational equillibrium

Answer 1

Net Torque Must Be Zero. The second condition necessary to achieve equilibrium involves avoiding accelerated rotation (maintaining aconstant angular velocity ). A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it.

Answer 2

For a rigid body to be in a complete state of equilibrium it must first be in a state of translational equilibrium where the sum of all of the forces equals zero.Then, we must also place it in a state of rotational equilibrium where the sum of all of the torques equals zero. For horizontal beams in the plane of the page, the torques will either result in a clockwise (cw) rotation or a counterclockwise (ccw) rotation.
