Use a computer program to assist in the design problems in Problem 5.67.

The shaft in Figure P5–67 supports a winch load of 780 lb and a torsional moment of 7800 lb-in. at F (26 inches from the center of the bearing at A). In addition, a radial load of 500 lb and an axial load of 400 lb act at point E from a worm gearset. Assume the maximum stress in the shaft cannot be larger than that obtained from the maximum distortional energy theory with a factor of safety of 2.5. Also make sure the angle of twist is less than 1.5 deg between A and D. In your model, assume the bearing at A to be frozen when calculating the angle of twist. Bearings at B; C, and D can be assumed as simple supports. Determine the required shaft diameter.
