An ideal cable supporting loads in a vertical plane can resist which type of internal force?
Correct answer: C. Tension only
- A. Bending only
- B. Compression only
- C. Tension only
- D. Torsion only
Explanation
A flexible cable has negligible bending and flexural stiffness, so it carries axial tension along its changing shape. It cannot sustain compression because it would become slack rather than push against the load.

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.
