Moment of inertia of a disc about a diameter is $I .$ Find the moment of inertia of disc about an axis perpendicular to its plane and passing through its rim?

Options:

Answer:

Solution:

Moment of inertia of a disc about a diameter is $\frac{1}{4} M R^{2} = I$ (given) $∴ M R^{2} = 4 I$ Now, required moment of inertia $= \frac{3}{2} M R^{2}$ $= \frac{3}{2} (4 I) = 6 I$
