A capstan is used to hold a large ship to it's mooring via a heavy rope. As the tide goes out the ship (and current) exerts a 20000 lb force on the rope. How many wraps around the capstan are required such that one person exerting 100lbs of force can keep the ship at its mooring. Assume the friction coefficient between the rope and capstan is 0.2.
