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 × 10-4 m2 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.
