Draw the influence lines for the vertical and horizontal reactions, \(A_{X}\) and \(A_{Y}\), at support \(A\) and the bar forces in members \(A D, C D\), and \(B C\). If the truss is loaded by a uniform dead load of \(4 \mathrm{kips} / \mathrm{ft}\) over the entire length of the top chord, determine the magnitude of the bar forces in members \(A D\) and \(C D\).
