A hawser is wrapped two full times around a bollard. by exerting an 80 pound force on the free end of the hawser a dockworker can resist a force of 5000 on the other end of the hawser. Determine the....
(a) the coefficient of statics friction between the hawser and the bollard.
(b) the number of times the hawser should be wrapped around the bollard if a 20000 pound force is to be resisted by the same 80 pound force
