2. A steel bar of 750 mm2 cross-sectional area is placed between two aluminum bars, each of 500 mm2 cross-sectional area. The ends of the bars are attached to a rigid support on one side and a rigid thick plate on the other. Assume that for steel E, = 210 GPa , (o,) = 240 MPa (o,) = 320 MPa Assume that both material exhibit elastic-perfectly plastic and for aluminum E= 70 GPa, !! al behavior. Determine the yield load, P, and the corresponding yield displacement, Sy.
