1. Jack & Jill went up the hill to fetch a pail of water. At the well, Jill used a force of 20.0 N to turn the
crank handle of radius 0.400 m to rotate the axle of radius 0.100 m, so she could raise the 60.0 N bucket
of water. A) What is the ideal mechanical advantage of the wheel? B) What is the actual mechanical
advantage of the wheel? c) What is the efficiency of the wheel? (IMA = 4.0, AMA = 3.0, Eff = 75%).show your work for all parts of the question.
