Questions 5 through 8 refer to the situation depicted below. Power is delivered by
a motor (not shown) via a belt to the pulley at A, causing the shaft to rotate in
steady-state at 3600 rpm against a load imposed at pulley B. On pulley B the slack
side of the belt exerts a force that is 15% of the force on the tight side.
