1. a) The sailors on a yacht are part way through a race across Lake Superior when their mainsail tears. They quickly take it down and then attach a new one to the rigging.In doing this, they use a wheel and axle mechanism to raise the new sail. The handle has a radius of 17.0 cm and the axle, itself, has a radius of 6.50 cm.What force must a sailor apply to lift the sail with this device, if the sail weighs 1030 N?

b) What is the Mechanical Advantage of this wheel and axle mechanism?
