(a) InFigure P10.15 compute the vertical and horizontal components of displacement of joint Eproduced by the loads. The area of bars AB, BD,and CD = 5 in2; the area of all other bars = 3 in2.E= 30,000 kips/in2. (b)If bars ABand BD are fabricated  in too long and support D settles 0.25 in, compute the vertical displacement of joint E. Neglect all the applied loads.
