The composite beam shown in the figure is simply supported and carries a total uniform load of 90 kN/m on a span length of 4 m. The beam is built of a wood member having cross-sectional dimensions 150 mm x 250 mm and two steel plates of cross-sectional dimensions 50 mm × 150 mm. The moduli of elasticity are Es = 214 GPa and Ew = 11 GPa. (a) Determine the maximum stress in the steel. (Disregard the weight of the beam. Round to one decimal place.) (b) Determine the maximum stress in the wood. (Disregard the weight of the beam. Round to one decimal place.)
