The section of shaft shown in the figure is to be designed to approximate relative sizes of D=1.5d, and r=0.125d. The shaft is to be made of AISI 1035 CD steel and the groove is machined. The shaft is subjected to a completely reversed bending moment of 800 lbf.in, accompanied by a steady torque of 500 lbf.in. The shaft is to be used at 400°F and is expected to have a reliability of 0.99. Use a design factor of 2 and size the shaft for an infinite life using the Modified Goodman criterion. Determine the minimum diameter 'd'.
