Problem 1.03 An aluminum rod is rigidly attached between a steel rod and a bronze rod as shown in Fig. P-108. Axial loads are applied at the positions indicated. Find the maximum value of P that will not exceed a stress in steel of 140 MPa, in aluminum of 90 MPa, or in bronze of 100 MPa. Steel Aluminum A=400 mm² A=500 mm² Bronze A = 200 mm² 4P 2P Solution 1.03 2.5 m 2.0 m 1.5 m Note: Unit conversion - If MPa (stress) is multiplied by mm² (area), the result is in Newton (force) Draw the axial load diagram first. Start drawings the axial load diagram from the free end (not the fixed end). Calculate the maximum force independently in each member and see which has the minimum load capacity. Resolve and submit.
