Problem

A thin uniform rod of length

L

and mass

M

has three axes of rotation perpendicular to the rod: P: through its centre, Q: through a point at a distance

\dfrac{L}{4}

from the centre, R: through one end of the rod. Which axis gives the largest moment of inertia? a)

\text{Axis P}

\text{Axis Q}

\text{Axis R}

\text{All three axes give the same value}
