Question

The mechanism shown is used to raise a 4.2 kg bucket of water out of well. A rope is wrapped around a wooden cylinder that has a radius of 0.13 m, a length of 0.56 m, and a density of 700 kg/m³. The crank handle is 0.38 m long. A. Determine the tension in the rope when the bucket of water is being raised with an acceleration of 0.80 m/s2. (include units with answer). B. Determine the magnitude of the force that needs to be applied to the crank to raise the bucket of water with an acceleration of 0.80 m/s².
