Meaning for the rotational equilibrium is :
When an object is in equilibrium, it is not moving or rotating. The object's linear and angular accelerations are both zero.
* The sum of all the torques acting on a system must be equal to zero.
* The sum of the clockwise torques must be equal to the sum of the counterclockwise torques.
* The pivotal axis can be chosen to be any point inside or outside the object.
* It useful to observe that choosing the pivot point through the line of action of a force eliminates that force from the equilibrium torque equations. This often simplifies things.
summation of torque = 0 at any point
