directions. The space truss is subjected to point loads 20 kN in z direction at joints E and F, and 40 kN in x-direction at joint F. (a) Determine force in all members meet at joint F and state if the members are in tension or compression. (b) (14marks) If the forces in member AB, and AC are 0 kN and 20.6 kN (tension) respectively, determine reaction at A.
