What is the Principle of moments ?
Principle of moments states that for a body to be in equilibrium, the sum of the clockwise moments about any equals the sum of the anti-clockwise moments about the same point.
3 of 6
What are the conditions of a body in equilibrium ?
The resultant force acting on it is Zero and the total moment is Zero.
