Determine the force in members GF, CF, CD of the symmetric roof truss and indicate whether the members are in tension or compression.

• A. CD = 1.783 kN C, CF = 0, GF = 1.427 kN T
• B. CD = 3.48 kN C, CF = 00904 kN T, GF = 1.783 kN T
• C. CD = 2.79 kN C, CF = 0.723 kN T, GF = 1.427 kN T
• D. CD = 2.23 kN C, CF = 0, GF = 1.783 kN T
