WebSep 21, 2024 · Moments of inertia are always calculated relative to a specific axis, so the moments of inertia of all the sub shapes must be calculated with respect to this same axis, which will usually involve applying the parallel axis theorem. (10.4.1) I = ∑ i = 0 n ( I) i = ∑ i = 0 n ( I ¯ + A d 2) i. The method is demonstrated in the following examples. WebSep 17, 2024 · The dimensions of the ring are Ri = 30 mm, Ro = 45 mm, and a = 80 mm. Answer Solution The parallel axis theorem can also be used to find a centroidal moment of inertia when you already know the moment of inertia of a shape about another axis, by using the theorem ‘backwards’, I = ˉI + Ad3 → ˉI = I − Ad2. Example 10.3.3.
