Solve Prob. 11–67 if the rods are rotated 90 so that both rods rest on the supports at A (pin) and B (roller).

(Reference Problem 11-67)

The two solid steel rods are bolted together along their length and support the loading shown. Assume the support at A is a pin and B is a roller. Determine the required diameter d of each of the rods if the allowable bending stress is σ_allow = 130 MPa .
