A solid steel shaft supports loads PA = 570 N and PD = 430 N, as shown. Assume L1 = 250 mm, L2 = 510 mm, and L3 = 230 mm. The bearing at B can be idealized as a roller support and the bearing at C can be idealized as a pin support. If the allowable bending stress is 38 MPa, determine the minimum diameter d that can be used for the shaft.
