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

The crane shown in the figure is lifting a 226-kg crate upward with an acceleration of 4.52 m/s². The cable from the crate passes over a
solid cylindrical pulley at the top of the boom. The pulley has a mass of 148 kg. The cable is then wound onto a hollow cylindrical drum
that is mounted on the deck of the crane. The mass of the drum is 267 kg, and its radius (the same as that of the pulley) is 0.237 m. The
engine applies a counterclockwise torque to the drum in order to wind up the cable. What is the magnitude of this torque? Ignore the
mass of the cable.
