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