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… WebParallel Axis Theory. To determine the Second Moment of Area about an axis which is parallel to a centroid axis and at a distance k . Iw = I + A.k2. Notes. C x , C y = Centroid Co-ordinates.
