An аluminum [E = 10,130 ksi] bаr is bоnded tо а steel [E = 26,350 ksi] bar tо form a composite beam as shown. The composite beam is subjected to a bending moment of M = +210 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.611 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.1917 in.4, find the magnitude of the maximum bending stress in the steel.
