The three-bar truss problem in figure 1.23 is under a vertical load of \(F_{y}=-5,000 \mathrm{~N}\) at node 4 in addition to the temperature change. Solve the problem by

(a) applying \(F_{y}\) and \(\Delta T\) at the same time, and

(b) superposing two solutions: one from applying \(F_{y}\) and the other from changing temperature \(\Delta T\).
