(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Derive an expression for the moment of inertia about the axis of symmetry for

a cylinder of mass M , length L and radius a, where the mass density decreases as a

function of distance from the axis as 1/r

2. Relevant equations

3. The attempt at a solution

1) am i right in thinking this would just be the same as the MOI of a disk of same mass?

and is the answer 2pi/3 a^3 or alternatively 1/3 M/L a^3
