A body is said to be in equilibrium if it continues its state of rest or its state of uniform motion. Equilibrium can be categorized in two ways:
1) Static equilibrium: If a body is at rest and remains at rest, then the equilibrium is said to be static equilibrium.
2) Dynamic equilibrium: If a body is initially moving with some velocity and it continues its motion rectilinearly with the same velocity, or if the body is rotating with some initial angular velocity and the angular velocity remains constant, then the body is said to be in dynamic equilibrium.
If the velocity and angular velocity of the body, either zero or non-zero, remain constant with time, then acceleration and angular acceleration are zero.
For rectilinear motion, if the acceleration is zero, then by Newton’s second law the net force is also zero.
Similarly, for rotatory motion, if angular acceleration is zero, then by Newton’s second law for rotation net torque is also zero.
Equilibrium can further be classified as follows:
1) Translational equilibrium: If the net force acting on a body is zero, then the body is said to be in translational equilibrium. In such a case, the center of mass of the body remains either at rest or moves rectilinearly with constant velocity.
2) Rotational equilibrium: If the net torque acting on a body is zero, then the body is said to be in rotational equilibrium. In such a case, the angular velocity of the body remains constant.
