The cross-sectional dimensions of a beam are shown. Assume bf=2.5 in., tf=tw=0.125 in. and d=3.875 in. (a) If the bending stress at point K is 2760 psi (T), determine the internal bending moment Mz acting about the z centroidal axis of the beam. (b) Determine the bending stress at point H (positive if tension, negative if compression).
