For the space trusses shown in Figures P3–40 and P3–41,
determine the nodal displacements and the stresses in each element. Let E = 210
GPa and A = 10 10

for all elements. Verify force
equilibrium at node 1. The coordinates of each node, in meters, are shown in
the figure. All supports are ball-and-socket joints.
