Physics - Rotation Question with Solution | TestHub

A circular disc $D_1$ of mass $M$ and radius $R$ has two identical $\mathrm{discs}{D}_2$ and $D_3$ of the same mass $M$ and radius R attached rigidly at its opposite ends (see figure). The moment of inertia of the system about the axis OO', passing through the centre of $D_1$, as shown in the figure, will be
