Determine the force in each member of the truss shown. State whether each member is in tension or compression.

Answers:

Reactions: $H_x=0kN,H_Y=12kN($upward$)A_Y=12kN($upward$)$

$F_{GH}=F_{AC}=12kNT,F_{FH}=F_{AB}=15kNC$

$F_{EF}=F_{BE}=0\mathrm{.}714kNC,F_{DF}=F_{BD}=11\mathrm{.}93kNC$

$F_{EG}=F_{CE}=12kNT,F_{DE}=0\mathrm{.}856kNT$

$F_{BC}=F_{FG}=0kN,$
