Rotational Motion · Moment of inertia
A uniform solid cylinder of length and radius has moment of inertia about its axis equal to . A small concentric cylinder of length and radius carved from this cylinder has moment of inertia about its axis equal to . The ratio is .
We corrected a printing error in the original paper
Source printed “A small co-centric cylinder” and “about its axis equals to ”.
