Determine the force in members BCBC$,$ CFCF$,$ and FEFE. State if the members are in tension or compression. Take that P$1$P$1=480$ lblb and P$2$P$2=900$ lblb $.($Figure $1)$

$1.$ Determine the force in the member CF$,$ and state if the member is in tension or compression.

$2.$ Determine the force in the member FE$,$ and state if the member is in tension or compression.

$3.$ Determine the force in the member BC$,$ and state if the member is in tension or compression.
