Polar Moment of Inertia in Residual Stresses Formulas

Polar Moment of Inertia is a measure of an object’s resistance to torsion, which is the twisting force that causes it to rotate around a pivot point. And is denoted by J. Polar Moment of Inertia is usually measured using the Millimeter⁴ for Second Moment of Area. Note that the value of Polar Moment of Inertia is always negative.
