Question

What is the principle of moments?

Answer 1

1. According to the principle of the moment, if the body is balanced, the total clockwise moment about a point is equal to the total anticlockwise moment about the same point.
2. The moment is given by the product of force and the perpendicular distance from the applied force to the object.
3. Mathematically,

Moment = Force x perpendicular distance
