Jackson finds an old well with a rope, bucket, a shaft that spools the rope, and a large crank wheel that turns the shaft to bring up the bucket of water. The bucket and the water have a total mass of 10.33kg, the shaft has a diameter of 15cm, and the crank wheel has a radius of 0.625m. Ignoring the mass of the rope, use torque to find the tangential force on the crank wheel required to lift the bucket and the water at a constanst speed.

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.
