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… Web7 aug. 2024 · Let us now calculate the geometric moment of inertia of a uniform solid sphere of radius a, mass m, density ρ, with respect to the center of the sphere. It is. ι = ∫spherer2dm. The element of mass, dm, here is the mass of a shell of radii r, r + dr; that is 4πρr2dr. Thus. ι = 4πρ∫a 0r4dr = 4 5πρa5. ι = 3 5ma2.
