Question 523: Centre of Mass and Rotational Motion

Question

The moment of inertia of uniform circular disc is maximum about an axis perpendicular to the disc and passing through point

Accepted Answer

Moment of Inertia $(\mathrm{I})=\mathrm{I}_{\mathrm{CM}}+\mathrm{Md}^2$
where $d$ is distance of axis from COM
The $\mathrm{I}_{\mathrm{CM}}$ and M is same for all the points and only ' d ' is varying
As axis B is having more distance from COM and thus will have more moment of inertia.
