Web23 jan. 2024 · Eigenvalues quantify inertia along principal axes, their ordering is irrelevant as long as the correspondance with eigenvectors is preserved. Don't be confused by the fact that they are equal to diagonal Ixx,Iyy,Izz elements in your example, the eigenvalues have nothing to do with x-y-z coordinates, in particular, they are orientation-agnostic. WebMoment of inertia, denoted by I, measures the extent to which an object resists rotational acceleration about a particular axis, it is the rotational analogue to mass (which determines an object's resistance to linear acceleration ). The moments of inertia of a mass have units of dimension ML 2 ( [mass] × [length] 2 ).

WebThe axes of such a special coordinate system are called the principal axes, while the diagonal elements Ij given by Eq. (24), the principal moments of inertia of the body.
