Torsion Constant for Circle Cross-section formula
\( J = \pi \; d^4 \;/\; 32 \) (Torsion Constant for Circle Cross-section) \( d = \sqrt[4]{ 32 \; J \;/\; \pi } \)
Symbol	English	Metric
\( J \) (Greek symbol alpha) = torsion constant	\(in^4\)	\(mm^4\)
\( \pi \) = Pi	\(3.141 592 653 ...\)
\( d \) = diameter of the circle	\(in\)	\(mm\)
