This quantity can be determined for continuous bodies by integrating the radius squared with respect to mass.
One quantity known by this name is found in the numerator of the definition of the section modulus. That quantity known by this name is multiplied by Young's modulus to give the deflection of a cantilevered beam. The square root of that quantity known by this name is divided by mass to give the radius of gyration about an axis. That quantity is also known as its "area" type and measures a beam's ability to resist bending. This quantity plus mass times the distance to another axis squared gives this quantity about that other axis by the parallel axis theorem. This quantity can be determined for continuous bodies by integrating the radius squared with respect to mass. This quantity is a measure of an object's resistance to changes in its rotation. For 10 points, name this rotational analog of mass, symbolized I.
One quantity known by this name is found in the numerator of the definition of the section modulus.
