Part B

As shown, a truss is loaded by the forces $P_1=491lb$ and $P_2=194lb$ and has the dimension $a=11\mathrm{.}0ft.$

Determine $F_{CC}$ and $F_{GH},$ the magnitudes of the forces in members $CG$ and $GH,$ respectively, using the method of sections. Assume for your calculations that each member is in tension, and include in your resp each force that you obtain by applying this assumption.

Express your answers numerically in pounds to three significant ingures separated by a comma.
