Problem 5: For the space truss structure shown in figure below, determine the displacements of node 4 using the stiffness method. Also determine the stresses in each element. The coordinates of each node, in inches, are shown in the figure. Nodes 1-3 are supported by ball-and-socket joints (fixed supports). A = 6 in and E = 30 106 psi .)
