The composite beam shown is formed by bonding together a brassrod and an aluminum rod of semicircular cross sections. The modulusof elasticity is 15 3 106 psi for the brass and 10 3 106 psi forthe aluminum. Knowing that the composite beam is bent about ahorizontal axis by couples of moment 8 kip ? in., determine themaximum stress (a) in the brass, (b) in the aluminum.
