The cross-sectional dimensions of a beam are shown. Assume bf=3.375 in., tf=tw=0.3125 in. and d=3 in. (a) If the bending stress at point K is 2050 psi (T), determine the internal bending moment Mz acting about the z centroidal axis of the beam. (b) Determine the bending stress σH at point H (positive if tension, negative if compression).
