For the truss shown in Figure P3–45, use symmetry to
determine the displacements of the nodes and the stresses in each element. All
elements have E = 200 GPa. Elements 1, 2, 4, and 5 have A = 10 10

and element 3 has A = 20 10

. Let dimension a = 2 m
and P = 40 kN. The supports at nodes 1 and 4 are defined.
