The moment inertia of an ellipse disc of uniform mass Desribution to mass 'M' major axis 'r' minor axis 'd' about its axis is
The moment of inertia of a uniform elliptical disc about its center and perpendicular to the plane of the disc (the z-axis) is given by the following formula:
I = \frac{1}{4} M \left( r_{\text{major}}^2 + r_{\text{minor}}^2 \right)
Where:
- is the mass of the disc,
- is the length of the major axis,
- is the length of the minor axis.
