Show transcribed image text The 6.8 x 13.6-in. timber beam has been strengthened by bolting to it the steel reinforcement shown. The modulus of elasticity for wood is 1.7 x 10^6 psi and for steel 29 x 10^6 psi. Knowing that the beam is bent about a horizontal axis by a couple moment of 448 kip . In., determine the maximum stress in the steel.
