Four identical rings, each of mass m and radius R, form the shown AUDI pattern. The moment of inertia about the tangent axis is . Find a.

Answer:
3
Solution:
Adjacent ring centres are separated by 3R/2, and the axis is tangent to the fourth ring.
Using I= mR²/2+md² for each ring and summing gives 111mR²/2.
Given I=37a mR²/2, we get a=3.
