For a pin-ended prismatic column of length L, the Euler critical buckling load is
Correct answer: A. π²EI/L²
- A. π²EI/L²
- B. 2π²EI/L²
- C. π²EI/(2L)²
- D. 4π²EI/L²
Explanation
Both ends are pinned, so the effective length equals the actual length L. Substitution into Euler's formula gives Pcr = π²EI/L², while the other expressions correspond to different effective lengths or incorrect multipliers.

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.
