The mechanism shown in the figure is used to raise a 4.0 kg bucket of water out of a 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 $kg/m^3$. The crank handle is 0.30 m long. The bucket is raised out of the well with an acceleration of 0.74 $m/s^2$.
Part A
Determine the tension in the rope when the bucket of water is being raised.
42.2 N
Part B
Determine the magnitude of the force that needs to be applied to the crank to raise the bucket of water.
18.3 N
