Solve all problems using the finite element stiffness method.

For the rigid frame shown in Figure P5–1, determine (1) the displacement components and the rotation at node 2, (2) the support reactions, and (3) the forces in each element. Then check equilibrium at node 2. Let E = 30 × 10⁶ psi, A = 10 in², and I = 500 in⁴ for both elements.
