Concept explainers

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

3. A 15-kg uniform beam is 3.0 m long and is pivoted 1.0 m from the left end. A 35 kg
child sits on the left end of the beam 0.60 m from the pivot. How far from the pivot must
a 20 kg child sit in order for the beam to be in equilibrium?
