Under the ideal assumptions used in truss analysis, the members of a pin-jointed truss primarily carry
Correct answer: D. Axial force only
- A. Uniform transverse pressure
- B. Bending moment only
- C. Shear force and torsion
- D. Axial force only
Explanation
Ideal truss members are connected by frictionless pins and loads act at the joints, so each member behaves as a two-force member. Its internal action is therefore tension or compression along its axis.

About Structural Analysis
Structural analysis determines how beams, frames, trusses and arches carry loads through reactions, shear forces, bending moments, axial forces and deflections. It covers free-body diagrams, equilibrium equations, determinacy, influence lines and methods such as slope deflection, moment distribution and virtual work, while distinguishing analysis of a structure from its design.
