For rotational equilibrium, the sum of all the torques acting on the body must be zero. This note provides us an information on co-planar force, Moment of a force, clockwise and anticlockwise moments and torque.
The centre of gravity (CG) of a body is a point where the weight of the body acts and total gravitational torque on the body is zero. This note provides us an information on centre of gravity and centre of mass.
This note provides us an information about Equilibrium of Rigid Bodies
For an object to be in translational equilibrium the vector sum of the forces acting on it must be zero. This note provides us an information on the equilibrium of rigid bodies.
A rigid body will be in equilibrium if the following two conditions are met.
The sum of the forces acting on the body must be zero.
The net torque acting on the body must be zero.
when a body is in transitional equilibrium, it ie either at rest or it is moving with constant velocity.
There are four types of state of equilibrium . the are Stable equilibrium ,Unstable equilibrium , Neutral equilibrium,
