(a)In Figure P8.15 compute the vertical and horizontal components of displacement of joint E produced by the loads. The area of bars AB, BD, and CD = 5 in. 2 ; the area of all other bars = 3 in. 2 . E = 30,000 kips/in. 2 . (b) If bars AB and BD are fabricated 3 4 in. too long and support D settles 0.25 in., compute the vertical displacement of joint E. Neglect all the applied loads.
