Given $F=213lb$ for the following truss structure, force in AC is: $q,$ lb$.$ Calculate your answer to first digit place. Write down all the steps to get the most credit.

Following steps are for your reference if you want to follow:

For the whole structure, draw FBD$,$ write down necessary E$-$of$-$E$,$ and solve for reaction force$($s$)$ you will need;

For Joint C$,$ draw FBD$,$ write down E$-$of$-$E$,$ and solve for the force in the two$-$force member AC$.$
