For the space truss subjected to a 1000-lb load in the x direction, as shown in Figure P3-42, determine the displacement of node 5. Also determine the stresses in each element. Let A = 4 in.2 and E = 30 × 106 psi for all elements. The coordinates of each node, in inches, are shown in the figure. Nodes 1-4 are supported by ball-and-socket joints (fixed supports)?
