Problem 6.3-4 The composite beam shown in the figure is simply supported and carries a total uniform load of 50 kN/m on a span length of 4.0 m. The beam is built of a wood member having cross-sectional dimensions 150 mm 250 mm and two steel plates of cross-sectional dimensions 50 mm 150 mm. Determine the maximum stresses s s and s w in the steel and wood, respectively, if the moduli of elasticity are E s 209 GPa and E w 11 GPa.
