An apparatus for measuring the mechanical equivalent of heat uses a crank to turn a small aluminum cylinder, which is being retarded by a belt. Friction with the belt heats up the cylinder, and the work done is then set equal to the heat gained by the cylinder. In one such experiment, the radius of the cylinder is 3.00 cm, the tension on one side of the belt is 50.0 N and on the other it is zero N. How much work is done turning the crank 212 times?
