A space truss is restrained at joints O, A, B, and C, as shown in the figure. Load P is applied at joint A and load 2P acts downward at joint C.

(a) Find reaction force components A_x, By, and B_z
in terms of load variable P.

(b) Find the axial force in truss member AB in terms of load variable P.
