Euler's Buckling Formula
Critical Load: Pcr = π²EI/(KL)²
Effective Length: Le = KL
Slenderness Ratio: λ = Le/r
Critical Stress: σcr = Pcr/A
End Condition Factors (K)
Pinned-Pinned: K = 1.0
Fixed-Free: K = 2.0
Fixed-Pinned: K = 0.7
Fixed-Fixed: K = 0.5
Variables
Pcr = Critical buckling load (N)
E = Elastic modulus (Pa)
I = Moment of inertia (m⁴)
K = Effective length factor
L = Actual length (m)
r = Radius of gyration (m)
A = Cross-sectional area (m²)
