For the truss shown in Figure P3–45, use agreement to determine the displacements of the nodes and the stresses in each part. All elements bear E = 200 GPa. Elements 1, 2, 4, and 5 bear A = 10 104 m2 and part 3 has A = 20 104 m2. Let extent a = 2 m and P = 40 kN. The supports at nodes 1 and 4 are defined.
