Extracted text: A beam is constructed of two angle sections, each L5 x 3 x 1/2, which reinforce a 2 x 8 (actual dimensions) wood plank (see the cross section shown in the figure). The modulus of elasticity for the wood is E, = 1.2 x 10° psi and for steel is E, = 30 x 10° psi. Assume that the component parts of the beams are securely bonded by adhesives or connected by fasteners. Also, use the transformed-section method in the solutions. 2 x 8 wood plank 5 in 3 in. Steel angles Find the allowable bending moment Mallow for the beam if the allowable stress in the wood is Ow = 1300 psi and in the steel is o = 10,500 psi. Dimensions and properties of the angles: I, = 9.43 in.*, d = 1.74 in. and A, = 3.75 in." (Note: Disregard the weight of the beam). Round your answer to one decimal place. Mallow = k. in.
