WebThe unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square. In the U.S. customary system, m is in slugs (1 slug = 32.2 pounds) and r in feet, with I expressed in terms of slug-foot square. The moment of inertia … Web7.4.1 Intro to Mass Moment of Inertia. Mass moment of inertia, or inertia as it will be referred to from here on, is resistance to rotation. The bigger the inertia, the slower the rotation. ∑M = I α ∑ M = I α. Inertia is always positive and has units of kgm 2 or slugft 2. For an infinitesimal unit of mass, the inertia depends on how far ...
