An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in the figure. Axial loads are applied at the positions indicated. Build diagrams of longitudinal forces, normal stresses, displacements and find the maximum value of P that will not exceed allowable stresses in steel (140 Mpa), in aluminum (90 Mpa), or in bronze (100 Mpa). Aluminum A = 400 mm² Bronze Steel A = 200 mm² A = 500 mm² 4P 2.5 m 2.0 m 1.5 m 2P
