Solve Problem by using a computer program.

For the rigid frame shown in Figure P5–20, determine (1) the nodal displacement components and (2) the support reactions. (3) Draw the shear force and bending moment diagrams. Let E = 30 × 10⁶ psi, I = 200 in.⁴, and A = 10 in.² for all elements, except as noted in the figure.
