Principal moments of inertia とは

Web引用. In classical mechanics, moment of inertia, also called mass moment of inertia, rotational inertia, polar moment of inertia of mass, or the angular mass, ( SI units kg · m²) … WebThis is not the case for angular momentum because moment of inertia is a 2nd order tensorial quantity. The inertia tensor of any physical object is symmetric and positive definite. Because the tensor is symmetric and positive definite, one can always find an orthogonal set of axes that make the off-diagonal elements of the inertia tensor vanish.
