Question

The axial load carring capacity of a long column of given material, cross-sectional area A, and length L, is governed by

• A. Strength of material only
• B. Its flexural rigidity only
• C. Its slenderness ratio only
• D. Both flexural rigidity and slenderness ratio

Answer 1

The correct option is D Both flexural rigidity and slenderness ratio

Load carring capacity of a long column is governed by Euler's formula.
$P_{cr}=\frac{{\pi }^{2}AE}{{\lambda }^2}$

Hence, for a given material (E), Area (A), load carrying capacity depends on $\left(\lambda \right)$ only.
