A space truss is restrained at joints A, B, and C, as shown in the figure. Load P acts in the 1z direction at joint B and in the 2z direction at joint C. Coordinates of all joints are given in terms of dimension variable L (see figure). Let P = 5 kN and L = 2 m.

(a) Find the reaction force components A_z and B_x.

(b) Find the axial force in truss member AB.
