When the person is moving,
P and Q are decrease.
Principle of Moment ( #turning effect)
The direction depend on the #pivot ( #Fulcrum )
When Equilibrium
1) Total clockwise moment = total anti-clockwise moment (net moment = 0 Nm)
2) Resultant force = 0 N (net force = 0N)
Direction
---> Clockwise moment
---> anti-clockwise moment
