FAQ

What is the Polar Moment of Inertia?
The Polar moment of Inertia is a shaft or beam’s resistance to being distorted by torsion, as a function of its shape. Polar Moment of Inertia is usually measured using the Meter⁴ for Second Moment of Area. Note that the value of Polar Moment of Inertia is always positive.
Can the Polar Moment of Inertia be negative?
No, the Polar Moment of Inertia, measured in Second Moment of Area cannot be negative.
What unit is used to measure Polar Moment of Inertia?
Polar Moment of Inertia is usually measured using the Meter⁴[m⁴] for Second Moment of Area. Centimeter⁴[m⁴], Millimeter⁴[m⁴] are the few other units in which Polar Moment of Inertia can be measured.
