If Mz = 3,000 lb-ft, find the magnitude of the bending stress at a point H. For the beam cross section, assume b = 3.750 in. c = 1.500 in. d = 2.625 in.t = 0.375 in. The centroid of the cross section is located 1.393 in. above the bottom surface of the beam. The moment of inertia about the z axis is 3.6198 in.4.
