Question

The moment of inertia of a disc of mass $M$ and radius $R$ about an axis, which is tangential to the circumference of the disc and parallel to its diameter is\

Professor PC Thomas Classes · Answer

(a) : Moment of inertia of a disc about its diameter $=\frac{1}{4} M R^{2}$\ Using theorem of parallel axes, $I=\frac{1}{4} M R^{2}+M R^{2}=\frac{5}{4} M R^{2}$.
