What is principle of moment
For a system to at equilibrium clockwise moment should be equal to ant clockwise moment
For a system to be in a rotational balance total clockwise moment and total antclockwise moment should be equal
The Principle of Moment states that when a system is in equilibrium the sum of its CLOCKWISE MOMENTS equals the sum of its ANTICLOCKWISE MOMENTS.
It states that for a system in equlibrium ,the sum of clockwise moment about a point is equal to the sum of anticlockwise moment about the same point.
For a system to be in rotational balance total clockwise moment must be equal to total anti clockwise moment
For a balanced system of forces,the sum of clockwise moments about a point is equal to the sum of anticlockwise moments about the same point
