The simple grid structure shown is supported by a vertical spring at node 2 and by fixed ends at nodes 1 and 3. It is subjected to the external moments shown plus a prescribed settlement of (0.05 in) at node 2. Determine the nodal displacements and reactions only at nodes 1 and 3. Show ALL intermediate matrices, assembled K and Kff. Use the general grid element stiffness matrix attached.
