Torsion Constant for Square Cross-section formula

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

\(\large{ a =  \sqrt[4]{  \frac{ J }{ 2.25 }   }   }\)

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