Lever ⇒ balanced or in equilibrium
Definition
Principle of moments states that when a body is in equilibrium, sum of clockwise moments about a pivot is equal to sum of anticlockwise moments about the SAME pivot #PhysicsDefinitions
Conditions for Equilibrium ⇒ for body to be stationary or in equilibrium ⇒ must not have any rotational or translational motion → no resultant forces or resultant moments acting on the body
Conditions for equilibrium:
- resultant moment on body is 0
- resultant force on body is also 0
