Calculate the moment of inertia of a disc about its any diameter ?

Explanation

To calculate the moment of inertia of a disc about its diameter, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**: We need to find the moment of inertia (I) of a disc of mass \( m \) and radius \( r \) about any of its diameters.

2. **Define Axes**: Consider the disc lying in the xy-plane with its center at the origin. The z-axis is perpendicular to the disc, passing through the center. The x and y axes are along the diameters of the disc.
