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
