State the principle of moments.
State the principle of moments. Name one device based on it.
Solution 1
When a number of like or unlike parallel forces act on a rigid body and the body is in equilibrium, then the algebraic sum of the moments in the clockwise direction is equal to the algebraic sum of the moments in the anticlockwise direction.
Solution 2
The principle of moments states that the total of the clockwise and anticlockwise moments is equal at equilibrium.
A physical balance works on the principle of moments.
