WebTorsion Constant (J) - also known as the polar moment of inertia or J, is a value that describes a material's resistance to twisting or torsional deformation. For the circular section: The Moment of Inertia of a circle about the centroidal axis is about two perpendicular axes in the same plane x-y will be: I x x = I y y = π d 4 64 ⇒ π r 4 4.

WebThe moment of inertia obtained from the perpendicular axis theorem is called the Polar Moment of Inertia.
