$|F_{AF}|=141\mathrm{.}421kN(C)$

$|F_{AB}|=110kN(C)$

$|F_{BF}|=30kN(T)$

$|F_{BC}|=110kN(C)$

$|F_{DE}|=56\mathrm{.}5684kN(T)$

$|F_{DC}|=40kN(C)$

$|F_{EC}|=40kN(C)$

$|F_{EF}|=40kN(T)$

$|F_{CF}|=98\mathrm{.}9950kN(T)$

PRACTICE QUESTION $6$

Consider the truss below. Determine the force in members $BC,CF,$ and $FE$ using the method of sections and state if the members are in tension or compression.
