The plane truss shown in the figure is hinge-supported at $\text{E}$ and $\text{F}$. The truss is subjected to vertical downward force at $\text{R}$ and horizontal force at $\text{G}$.
The force $\text{(in kN )}$ along with its nature in member $\text{JF}$ is
- $10 \sqrt{2}$ compression
- $10 \sqrt{2}$ tension
- $25 \sqrt{2}$ compression
- $25 \sqrt{2}$ tension
