WebIn physics and applied mathematics, the mass moment of inertia, usually denoted by I, measures the extent to which an object resists rotational acceleration about a particular axis, and is the rotational analogue to mass. Mass moments of inertia have units of dimension ML2 ( [mass] × [length]2). WebThe rotational inertia of a disk about its center of mass is given by: where M is the mass of the disk and R is the radius of the disk. See Figure 11.2. To find the rotational inertia experimentally, a known torque is applied to the object and the resulting angular acceleration is measured.
