Column Buckling ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು
Column Buckling ಎಂದರೇನು?
Euler column buckling predicts critical load at which slender columns fail by instability rather than material crushing. It's essential for structural safety.

Worked Examples
ಇನ್ಪುಟ್
E = 200 GPa, I = 2×10⁹ mm⁴, L = 4 m, K = 1 (pinned)
ಫಲಿತಾಂಶ
P_cr ≈ 2.47 MN (critical load)
Higher leads to buckling
Common Mistakes to Avoid
- ✕Using unsupported length instead of effective length
- ✕Neglecting lateral bracing effects on K
Frequently Asked Questions
Why do long columns fail at lower loads?
Buckling instability dominates; longer unsupported length reduces critical load dramatically (proportional to 1/L²).
What is effective length factor K?
K accounts for end conditions: K=0.5 (fixed-fixed), K=1 (pinned-pinned), K=2 (cantilever).
