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

2. Two equal forces act on a long uniform rod which can
rotate about its center. Describe an orientation of the two
forces such that the net force on the rod is zero but the net
torque on the rod is non-zero.
