As shown in Fig. 3–16a, beam OC is loaded in the xy plane by a uniform load of 50 lbf/in, and in the xz plane by a concentrated force of 100 lbf at end C. The beam is 8 in long.
(a) For the cross section shown determine the maximum tensile and compressive bending stresses and where they act.
(b) If the cross section was a solid circular rod of diameter, d = 1.25 in, determine the magnitude of the maximum bending stress.
