A stepped bar (i.e., varied cross-section area) is subjected to an axial (vertical) force of P = 108 (N) at node 2, as illustrated in Figure 1. Given the areas of the cross section of the steps are given by A1 = 0.1 m2 and A2 = 0.05 m2 and Young's modulii of E1 = 200 GPa and E2 = 70 GPa. Determine the maximum displacements of nodes 2 and 3
