Problem $4$

For the trussed structure below, find the support reactions at A and the force in members CD$,$ DF$,$ and CF$.$ The lengths of members AF$,$ FD$,$ DG$,$ and GB is ${5\mathrm{.}18}^{ft}.$ CF and EG is ${1\mathrm{.}34}^{ft}.$ State if the members are in tension $($T$)$ or compression $($C$).$ Use the method of sections. Note: $Ax$ and $Bx$ are not zero.
