The machine shaft shown in Figure P8.88/89 is made of 1020 cold-rolled steel. (See Appendix D for properties.) The major shaft diameter is D = 30 mm, the minor shaft diameter is d = 20 mm, and the radius of the fillet between the major and minor diameter sections is r = 3 mm. The fillets are located at x = 90 mm from C. Determine the maximum load P that can be applied to the shaft at C if a factor of safety of 1.5 is specified.
