Question: the 59 times 118in timber beam has been strengthened by...

Question details

The 5.9 x 11.8-in. timber beam has been strengthened by bolting to it the steel reinforcement shown. The modulus of elasticity for wood is1.8 x 106 psi and for steel 29 x 106 psi. Knowing that the beam is bent about a horizontal axis by a couple moment of39 kip in., determine the maximum stress in the steel. 5.9 in. 11.8 in 4.8 x in.
