torsion constant circle 1Torsion Constant for Circle Cross-section formula

\(\large{ J = \frac{\pi \; d^4}{32} }\)   

Where:

 Units English Metric
\(\large{ J }\)  (Greek symbol alpha) = torsion constant \(\large{\frac{lbf-ft}{rad}}\) \(\large{\frac{N-m}{rad}}\)
\(\large{ d }\) = diameter of the circle \(\large{in}\) \(\large{m}\)
\(\large{ \pi }\) = Pi \(\large{3.141 592 653 ...}\)
