고체역학 (Gere) — Tension, Compression, and Shear: Problem 1.3-16

1.3-16 A space truss is restrained at joints A, B, and C, as shown in the figure. Load P acts in the +z direction at joint B and in the -z directions 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.
