14.7 What bending moment will cause a maximum bend- ing stress of 10,000 psi in the beam with the cross sec- tion shown? 0.25 in. 0.5 in. 3 in. 0.25 in. 0.5 in. 2 in. PROB. 14.7/n14.23 The W33 x 221 steel simply supported beam is loaded with concentrated loads and uniform load as shown. Determine (a) the maximum tensile and compressive bending stress if P 150 kip and w = 10 kip/ft, and (b) the allowable uniform load w if the allowable bending stress is 24 ksi and P = 15w.
