Diagonalization of this rank 2 tensor quantity splits it into three principal components.
Diagonalization of this rank 2 tensor quantity splits it into three principal components. The values of the axes of Poinsot's ellipsoid are proportional to this quantity, which is equal to the square of the radius of gyration multiplied by the cross-sectional area. For solid objects, it can be directly calculated by integrating the differential mass times distance from the axis of rotation squared throughout the volume of the object. If this quantity is known at the center of mass, it can be calculated at another axis using the parallel axis theorem. For 10 points, name this quantity, the rotational analogue of mass, usually symbolized with a capital I.
