If Mz = 38600 lb-ft, find the magnitude of the bending stress at a point H. For the beam cross section, assume b = 8.750 in. c = 3.500 in. d = 6.125 in. t = 0.875 in. The centroid of the cross section is located 3.25 in. above the bottom surface of the beam. The moment of inertia about the z axis is 107.3 in.4.
