Question:

A hawser is wrapped two full turns around a bollard. By exerting a 320-N force on the free end of the hawser, a dockworker can resist a force of 20kN on the other end of the hawser. Determine

(a) The coefficient of static friction between the hawser and the bollard,

(b) The number of times the hawser should be wrapped around the bollard if an 80-kN force is to be resisted by the same 320-N force.
