Euler Buckling Load

Critical axial load at which a column buckles.

Formula

Pcr=π2EI(KL)2P_{cr} = \frac{\pi^2 E I}{(K L)^2}

Variables

EModulus
IMoment of inertia
KEffective length factor
LLength

Example

Longer columns buckle at lower loads

Did You Know?

Euler derived this buckling formula in 1757.
