Question: A windlass of 10-in. diameter is used to raise or lower a 160-lb load. The windlass is supported by two poorly lubricated bearings of 3-in.

A windlass of 10-in. diameter is used to raise or lower a 160-lb load. The windlass is supported by two poorly lubricated bearings of 3-in. diameter. Knowing that the coefficient of static friction between the shaft and the bearings is 0.50, determine the magnitude of the force P required for impending raising of the load.
