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} = 209GPA and E {w} = 11GPA (Disregard the weight of the beam) Steel 50 mm 50 kN/m Wood B Steel 50 mm 4.0 m 150 mm 250 mm
