The figure (not to scale) shows a representation of a hoisting system. A couple is applied to the gear at A, which drives the larger gear B and lifts the load L vertically. As shown, we want to raise the load by 32 ft. The system is initially at rest. A undergoes uniform angular acceleration for 4 seconds until it reaches a top angular speed of 145 rpm, at which point it maintains constant angular speed. Determine: (a) The number of revolutions of gear A before the load is raised (b) The number of revolutions of gear B before the load is raised (c) The time required to raise the load
