2. The pin-connected truss shown below is geometrically symmetric, but the loading of $7\mathrm{kN}$ and $12\mathrm{kN}$ is asymmetric. A) Identify all zero-force members. B) Determine the axial force in member GJ using the method of sections. Express your answer in terms of magnitude and either tension or compression. C) Determine the axial force in member GF using the method of joints. Express your answer in terms of magnitude and either tension or compression.
