torsion constant circle 1Torsion, abbreviated as T, is the stress of twisting of an object due to applied torque.



\(\large{ T = \frac{J}{r} \; \tau }\)   


\(\large{ T }\) = applied torque or moment of torsion

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

\(\large{ r }\) = distance between the rotational axis and the farthest point in the section

\(\large{ \tau }\) (Greek symbol tau) = maximum shear stress at the outer surface
