Problème 3
The 150 X 250-mm timber beam has been strengthened
by bolting to it the steel reinforcement shown. The modulus of elasticity for
wood is 12 GPa and for steel 200 GPa. Knowing that the beam is bent about
a horizontal axis by a couple of moment M = 60 kN-m , determine the max-
imum stress in (a) the wood, (b) the steel.
