Question: A beam is constructed of two angle sections, each L 5 x 3 x 1/2, which reinforce a 2 x 8 (actual dimensions) wood plank

A beam is constructed of two angle sections, each L 5 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 Ew = 1.2 x 106 psi and for the steel is Es = 30 x 106 psi.
Find the allowable bending moment Mallow for the beam if the allowable stress in the wood is Ïƒw = 1100 psi and in the steel is Ïƒs = 12,000 psi.
