What is Equilibrium
A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion
The general conditions for equilibrium are as follows
(i) The total force must be zero
(ii) The total torque about any axis must be zero.
In many cases it is convenient to consider torques about axes through the centre of gravity.
Types of equilibrium
We can divide the equilibrium into two categories With respect to the state of a body
1. Static equilibrium.
2. Dynamic equilibrium.
