Torsion Constant for Square Cross-section formula

\( J = 2.25 \; a^4 \)     (Torsion Constant for Square Cross-section)

\( a =  \sqrt[4]{  J \;/\; 2.25 }   \)

Symbol English Metric
\( J \)  (Greek symbol alpha) = torsion constant \(in^4\) \(mm^4\)
\( a \) = half the edge length of a square \(in\) \(mm\)
