Compute the horizontal displacement of joint B in Figure P9.28. The moment diagram produced by the 12-kip load is given. The base of the columns at points A and E may be treated as fixed supports. Hint: Begin by sketching the deflected shape, using the moment diagrams to establish the curvature of members. Moments in units of kip⋅ ft.
