A simple beam on a 10 ft span supports a uniform load of intensity 800 lb/ft (see figure). The beam consists of a wood member (4 in. X 11.5 in. in cross section) that is reinforced by 0.25 in. thick steel plates on top and bottom. The moduli of elasticity for the steel and wood are E, = 30 x 10° psi and E = 1.5 x 10° psi, respectively. Calculate the maximum bending stresses a, in the steel plates and o, in the wood member due to the uniform load. 0.25 in. 800 Ib/ft 115 in. 0.25 in. 10 ft
