![]() ![]() When calculating moments of inertia, keep in mind that it is an additive function and use the parallel and perpendicular axis theorems. In general, it may be difficult to express the moment of inertia of shapes with more complicated mass distributions and lack of symmetry symbolically. This happens most of the time when the mass density is constant, but it can also happen when the density varies throughout the object. The mass moment of inertia is also known as rotational inertia and, in some cases, angular mass.įor simple objects with geometric symmetry, the moment of inertia is frequently expressed in an exact closed-form expression. ![]() The second moment of area, which is used in beam calculations, should not be confused with it. The dimensions of mass moments of inertia are ML 2( × 2). It measures the extent to which an object resists rotational acceleration about a specific axis. The rotational analogue to mass (which determines an object’s resistance to linear acceleration) is the moment of inertia, denoted by I. ![]()
