For the steel truss and loading shown, using either the method of sections or joints, determine: 13. the FBD for the entire structure, 14. the reaction at \( \mathrm{A} \) (magnitude \( (\mathrm{kN}) \) and direction \( \left({ }^{\circ}\right) \) from the negative \( x \)-axis), 15. the magnitude of force \( \mathrm{F}_{\mathrm{BF}}(\mathrm{kN}) \), 16. the magnitude of force \( \mathrm{F}_{\mathrm{BG}}(\mathrm{kN}) \) and whether it is in tension or compression, 17. the magnitude of force \( \mathrm{F}_{\mathrm{AB}}(\mathrm{kN}) \) and whether it is in tension or compression.
