The mechanism shown in the figure is used to raise a crate of supplies from a ship's hold. The crate has total mass 48 . A rope is wrapped around a wooden cylinder that turns on a metal axle. The cylinder has radius 0.30 and a moment of inertia = 2.5 about the axle. The crate is suspended from the free end of the rope. One end of the axle pivots on frictionless bearings; a crank handle is attached to the other end. When the crank is turned, the end of the handle rotates about the axle in a vertical circle of radius 0.12 , the cylinder turns, and the crate is raised.
