(a) Draw the influence lines for the bar forces in members \(H C, H G\), and \(C D\) of the truss shown in Figure P12.32.

The load moves along the bottom chord of the truss.

(b) Compute the force in member \(\mathrm{HC}\) if panel points \(B, C\), and \(D\) are each loaded by a concentrated vertical load of 12 kips.
