torsion constant ellipse 1Torsion Constant for Ellipse Cross-section formula

\(\large{ J = \frac{\pi\;a^3\;b^3}{a^2\;+\;b^2} }\)   

Where:

\(\large{ J }\)  (Greek symbol alpha) = torsion constant

\(\large{ a }\) = semi-major axis of an ellipse

\(\large{ b }\) = semi-minor axis of an ellipse

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