Draw the influence lines for the forces in members AF, CF, CG of the Parker truss shown in the figure below. Live loads are transmitted to the bottom chord of the truss. Determine the maximum live force for tension or compression that can be developed in this member due to a concentrated live load of \( 12 \mathrm{kN} \)
