Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

A 20-kg board serves as seesaw for two children.
One child has a mass of 30-kg and sits 2.5 m from the

Two children are trying to balance on a seesaw, which includes a fulcrum and a board that is 10m long. Boy A has a mass of 50kg, and boy B has a mass of 35kg. How far from the pivot point should boy B be to maintain stable equilibrium?
A 5.2-m ladder rests against a wall as shown. The ladder has a mass of 27.6 kg. A 56.3-kg person stands on the ladder at a distance of 3.6 m from the bottom of the ladder. The foot of the ladder is 1.9 m from the bottom of the wall. Assume there is no friction between the ladder and the wall so that the force of the wall on the ladder is acting only in the horizontal direction. However, there is a friction force between the ladder and the ground. 1.) What is the force, in N, exerted by the wall on the ladder?
