The composite beam shown in the figure is simply supported and carries a total uniform load of 50 kN/m on a span of 4.0 m. The bearn is built of a wood member having cross sectional dimensions 150 mm x 250 mm and two steel plates of cross-sectional dimensions 150 mm x 50 mm. Determine the maximum stresses, in the steel and wood, respectively. If the moduli of elasticity are E {s} (Disregard the weight of the beam) = 209GPa and E {w)} = 11GPA Steel 50 mm 50 kN/m Wood Steel 50 mm 4.0 m 150 mm 250 mm
