As shown in the figure below, a bronze bar is affixed between a steel bar and an aluminum bar. Axial loads are applied at the positions indicated. If the largest value of P that will not exceed an overall deformation of 4.0 mm, or the following stresses: 150 MPa in the steel, 130 MPa in the bronze, and 90 MPa in the aluminum, determine the stress in the bronze. Assume that the assembly is suitably braced to prevent buckling. Use Est = 200 GPa, Eal = 70 GPa, and Ebr = 83 GPa.
