EXAMPLE 3-6 Figure 3-16 (a) Beam loaded in two planes; (b) loading and bending-moment diagrams in xy plane; (c) loading and bending-moment diagrams in xz plane. 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. 50 lbf/in 0 1600 lbf-in 400 lbf 50 lbf/in OB M.
