Five metal strips are bonded together to form the composite beam as shown in figure Q4. The modulus of elasticity is 230 GPa for the steel, 112 GPa for the brass, and 83 GPa for the aluminum. Knowing that the beam is bent about a horizontal axis by a couple of moment 2400 N.m, determine (a) the maximum stress in each of the three metals, (b) the radius of curvature of the composite beam.
