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. WebThe definition of (mass) moment of inertia of a point mass is I = r 2 m However in the real world you don't encounter point masses, but objects with non-zero volume (finite density). And leads to an integral to determine moment of inertia I = ∫ m r 2 d m = ∫ V ρ ( r) r 2 d V = ∫ x ∫ y ∫ z ρ ( x, y, z) ( x 2 + y 2 + z 2) d z d y d x
