However, for a disk, we have to take it as a special character. Generally, it is used as a base for building the moment of inertia expression for different other shapes, such as a cylinder or a sphere. Meanwhile, we can also find the moment of inertia of a circular disc with respect to different situations. They are as follows; 1. Solid disk
In general form, moment of inertia is expressed as I = m × r2. where, m = Sum of the product of the mass. r = Distance from the axis of the rotation. And, integral form: I = ∫dI = ∫0M r2 dm. ⇒ The dimensional formula of the moment of inertia is given by, M 1 L 2 T 0.
Moment of inertia is the property of the body due to which it resists angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation. Moment of Inertia Formula. Moment of Inertia (I) = Σ m i r i 2. where, m = Sum of the product of the mass.

The moment of inertia of a uniform-density disk rotating about an axle through its center can be shown to be (1/2)MR2. This result is obtained by using integral calculus to add up the contributions of all the atoms in the disk (see Problem 9.3). The factor of 1/2 reflects the fact that some of the atoms are near the center and some are far from ...
