A simply supported composite beam 3 m long carries a uniformly distributed load of intensity q = 9 kN/m (see figure). The beam is constructed of a wood member, 100 mm wide by 150 mm deep, reinforced on its lower side by a steel plate 8 mm thick and 100 mm wide. The modulus of elasticity is Ew = 11 GPa for the wood and Es = 203 GPa for the steel. q-9 kN/m 150 mm 8 mm 3 m- 100 mm (a) Find the maximum bending stress ow in the wood due to the uniform load, Round to one decimal place. MPa (b) Find the maximum bending stress og in the steel due to the uniform load. Round to one decimal place. MPa
