1. Now remove the element connecting nodes 2 and 4 in Figure P3–24. Then determine the nodal displacements and element forces.
2. Determine the displacement components at node 3 and the element forces for the plane truss shown in Figure P3–27. Let A = 3 in
2
and E = 30 106 psi for all elements. Verify force equilibrium at node 3.
