The 6 × 12-in. timber beam has been strengthened by bolting to it the steel reinforcement shown. The modulus of elasticity for wood is 1.8 × 106 psi and for steel, 29 × 106 psi. Knowing that the beam is bent about a horizontal axis by a couple of moment M = 448 kip.in., determine the maximum stress in the wood and in the steel. 6 in.- 12 in. C8 × 11.5 The maximum compressive stress in the block of wood is The maximum tensile stress in the steel is ksi. ksi (include a negative sign).
