A composite beam is constructed using a steel plate (14 mm ✕ 125 mm) with two wood beams (75 mm ✕ 125 mm) 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 = 6.80 kN · m. Calculate the maximum tensile and compressive stresses in the wood and steel if Ew = 11 GPa and Es = 200 GPa. (Enter your answers in MPa. Use the deformation sign convention. Use the general theory for composite beams described in the textbook.) maximum tensile stress in wood MPa maximum tensile stress in steel MPa maximum compressive stress in wood MPa maximum compressive stress in steel MPa
