1. Find the horizontal and vertical displacements of node 1 for the truss shown in Figure P3–21….


1. Find the even and perpendicular misunderstandings of node 1 for the truss shown in Figure P3–21. Assume AE is the similar for each component.

2. For the truss shown in Figure P3–22 work-out for the even and perpendicular components of misunderstanding at node 1 and particularize the stress in each component. Also confirm soundness makeweight at node 1. All components have A1 = 1 in2 and E = 10 106 psi. Let L =100 in.
