Question

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 = 458 kip·in., determine the maximum stress in the wood and in the steel.

The maximum compressive stress in the block of wood is ksi (include a negative sign).

The maximum tensile stress in the steel is ksi.

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
