Corisider:

$P_1=17kN*P_2=16kN$

When cutting the truss, do not cut at C$,$ in the middle of B & D$.$

Use the method of joints AND the method of sections to answer the following questions $($you are required to use both the method of sections and the method of joints in your calculations$)$:

Specify the Zero$-$force members in this truss.

Determine the force in members CD$,$ CF$,$ and GF of this truss.

Note that a Positive answer shows a Tension force and a Negative answer shows a Compression Force.
