Two wheels, A and B, are connected by a belt as in Fig. 11-29. The radius of B is three times the radius of A. What would be the ratio of the rotational inertias I A /I B , if (a) both wheels have the same angular momenta and (b) both wheels have the same rotational kinetic energy? Assume that the belt does not slip.

From the above observation we conclude that, if both wheels have the same rotational kinetic energy, then the ratio of rotational inertia would be \frac{1}{9}.
