Five metal strips, each of 0.5 x 1.5-in. cross section, are bonded together to form the composite beam shown. The modulus of elasticity is 30 x 106 psi for the steel, 15 x 106 psi for the brass, and 10 x 106 psi for the aluminum. Knowing that the beam is bent about a horizontal axis by a couple of moment 12 kip? in., determine (a) the maximum stress in each of the three metals, (b) the radius of curvature of the composite beam.
