A composite beam is constructed using a steel plate(0.5 in.x 6 in.) with two wood beams (3in. X 6 in.) on either side. The wood and steel are securely fastened to act as a single beam. The beam is subjected to a positive bending moment Mz=60 kip-in. Calculate the maximum tensile and compressive stresses in the wood and steel if E_w= 1500 ksi and E_s=29,500 ksi.
