Column Buckling Stress

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Column buckling stress, abbreviated as \(\tau\) (Greek symbol tau), is the allowable buckling stress of a column.

 

Column Buckling Stress formula

\(\large{ \sigma = \frac{ \pi^2 \; E }{ \left( \frac{ l }{ r } \right)^2   }  }\)  

Where:

\(\large{ \sigma }\) (Greek symbol sigma) = critical buckling of allowable stress of a column

\(\large{ r }\) = least radius of column

\(\large{ \pi }\) = Pi

\(\large{ l }\) = unsupported length of column

\(\large{ E }\) = Young's modulus
