For the space truss subjected to the 4000-lb load acting as shown in Figure P3-43 determine the displacement of node 4. Also determine the stresses in each element. Let A = 6 in2 and E = 30 × 106 psi for all elements. The coordinates of each node, in inches, are shown in the figure. Nodes 1-3 are supported by ball-and-socket joints (fixed supports).
