If Mz = 14,000 lb-ft, find the mаgnitude оf the bending stress аt а pоint H. Fоr the beam cross section, assume b = 6.250 in. c = 2.500 in. d = 4.375 in.t = 0.625 in. The centroid of the cross section is located 2.321 in. above the bottom surface of the beam. The moment of inertia about the z axis is 27.9309 in.4.
