Diagonal moments of inertia
Web慣性モーメント（かんせいモーメント、英: moment of inertia ）あるいは慣性能率（かんせいのうりつ）、イナーシャ I とは、物体の角運動量 L と角速度 ω との間の関係を示す量である。 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.

Moment 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 ([mass] × [length] ). It should not be confused with the second moment of area, which is used in beam calculations. The mass moment of inertia is often also known as the rotational inertia, a…
