Question

Constante Part A The mechanism shown in the figure (Figure 1) used to raise a crate of supplies from a ship's hold. The crate has total mass 38 kg Arope is wrapped around a wooden cylinder that turns on a metalade. The cylinder has radius 0 33 m and a moment of inertia-2.1 kg m? about the le. The crate is spended from the free end of the rope. One end of the sole plots on frictions bearings, a crank handle is attached to the other and When the crank is tumed, the end of the handle rotates about the axde in a vertical circle of radius 0.12 m, the cyinderturns, and the crate is raised What magnitude of the force applied tangentially to the rotating crank is required to raise the crate with an acceleration af 140 m/s (You can grote the mass of the rope as well as the moments of inertia of the ade and the crank) Express your answer using two significant figures WOMED ?
