I am using Newton's Second Law for rotational motion, ##rf = I\alpha##, where ##r## is the radius, ##f## is the frictional force, and ##\alpha## is the angular acceleration. By writing the equation in terms of I, I am able to get rid of ##f##, and ##\alpha##, leaving me with just ##\frac{R}{r}##.

Thank you! That was close to my original title, but then I changed it because of the nature of my question!

Homework Statement Wheels A and B as shown in the figure are connected by a massless belt that does not slip. The radius of A is R and the radius of B is r. What is the ratio of rotational inertias ##\frac{I_a}{I_b}## if the two wheels had the same angular momentum about their central axes...
