Question

A bucket filled with water has a mass of 58 kg and is attachedto a rope that is wound around a .120m radius cylinder. Whattorque does the bucket produce around the center of the cylinder?(Nm) This next prob is a separate question but its okay if you onlyget one of them. A bucket filled with water has a mass of 79 kg and is attachedto a rope that is wound around a .065m radius cylinder. Acrank with a turning radius of .10m is attached to the end of thecylinder. what minimum force directed perpendiculary to thecrank handle is required to raise the bucket? (N) A bucket filled with water has a mass of 58 kg and is attachedto a rope that is wound around a .120m radius cylinder.

Explanation / Answer

(a) torque = weight of bucket * radius ofcylinder =    58 * 9.80 * 0.120 =   68.21N-m . (b) torque from turning force = torque from weightof bucket .           F *0.10    =   79 * 9.80 * 0.065 .         F =   503.2 Newtons is the minimum necessary force
