The buckling load for a material depends on
- ASlenderness ratio and Poisson’s ratio
- BSlenderness ratio and area of cross section
- CModulus of elasticity and area of cross section
- DModulus of elasticity, area of cross section and slenderness ratioCorrect
Solution
Concept
Euler load
Formula
Pcr = π²EA/λ²
Step-by-step solution
1. Pcr = π² E I / L² = π² E A / λ².
Explanation
It depends on E, A and the slenderness ratio λ.
Why the other options are wrong
Poisson's ratio does not appear.
Shortcut
Pcr = π²EA/λ².
Correct answer: D) Modulus of elasticity, area of cross section and slenderness ratio
