WebExpert Answer. 9.10 To determine the mass moment of inertia for a thin disk, circular cylinder, and sphere, we need to use the following relationships: For a solid cylinder rotating about its central axis: I = ( 1 2) M R 2. For a solid sphere rotating about its center of mass: I = ( 2 5) M R 2. Here, M is the mass of the object, R is the radius ... WebThe formula calculates the Moment of Inertia of a filled circular sector or a sector of a disc of angle θ and radius r with respect to an axis going through the centroid of the sector and the center of the circle. The formula is valid for 0 ≤ θ ≤ π Related formulas Variables Categories Civil Engineering Statics External links Wikipedia
