For a prismatic column fixed at one end and free at the other, the Euler critical buckling load is
Correct answer: C. π²EI divided by 4L²
- A. π²EI divided by L²
- B. π²EI divided by 2L²
- C. π²EI divided by 4L²
- D. 4π²EI divided by L²
Explanation
A fixed-free column has an effective length of 2L. Substituting this into Euler's formula gives Pcr = π²EI divided by 4L².

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.
