7. Each truss member in Figure has a length of \( 4 \mathrm{~m} \). Find the forces in members BC, CG, and FG.
7. Force in members, \( \mathrm{E}_{\mathrm{y}}=34 \mathrm{KN} \uparrow \) and \( \mathrm{A}_{\mathrm{y}}=38 \mathrm{KN} \uparrow \mathrm{A}_{\mathrm{x}}=0 \)
\[
\begin{array}{l}
\mathrm{BC}=26.6 \mathrm{KN}(\mathrm{C}) \\
\mathrm{CG}=9.24 \mathrm{KN}(\mathrm{C}) \\
\mathrm{FG}=31.2 \mathrm{KN}(\mathrm{T})
\end{array}
\]
