Question
Find the moment of inertia of a hoop (a thin-walled, hollow ring) with mass $M$ and radius $R$ about an axis perpendicular to the hoop's plane at an edge.
Step 1
First, we need to consider a small mass element dm on the hoop. Since the hoop is thin-walled and hollow, all the mass elements are at a distance R from the center. Show more…
