A disk of mass M = 2.0 kg and radius R = 0.25 m is free to rotate about its center. Two forces, F1 = 1.0 N and F2 = 4.0 N are applied tangentially to the disk, as shown. 1. How fast is a point located on the edge of the disk moving at t = 2.5s? 2. How many revolutions has the disk made after t = 2.5 s, assuming it starts from rest?

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.
