This was an exam question that I got wrong, my teacher tried to explain it but it only left me more confused. I found some websites that also had explanations but they were also confusing.
"Derive the moment of inertia of a uniform disk which rotates along a central axis , radius R , disk thickness d, mass M , density p
I= R^2 dm"
I= 1/2*M*R^2 ?
The Attempt at a Solution
mass M = Pi*R^2*d*p
My teacher mentioned something about a third integral.
