Web26 feb. 2024 · Moment of inertia 1. Moment of Inertia ( I ) The property of an object that serves as a resistance to angular motion. 1 BY Usman Sajid Sohrani 2. Moment of Inertia ( I ) ≈ Mass • Moment of inertia is affected by both the mass and how the mass is distributed relative to the axis of rotation. Web17 sep. 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.
