Formula

P_cr = π² E I / (K L)²

K: end-restraint factor (pinned=1, fixed=0.5, cantilever=2)

How to Use

  1. Enter modulus E and second moment I.
  2. Enter length L and end factor K.
  3. Get critical buckling load P_cr.

Case Studies

Steel column E=200GPa

E=200e9, I=1e-6, L=2, K=1 → P_cr≈4.93×10⁵ N.

FAQ

How to pick K?

From end conditions: pinned-pinned K=1, fixed-fixed K=0.5, fixed-free K=2.
