Damn! wrote that in the wrong forum!

mods please move to introductory physics!

thanks

Hi,

I'm learning by myself physics of rigid bodies , and I find it kinda hard.

Well, I know calculating the moments of Inertia is useless cause You have a table with all the MoI.

This is not a specific problem i ran into but I'll write it anyway:

## Homework Statement

Calculate the Moment of inertia of a rotating(about it's center of mass) solid wheel of mass M( assume it's homogeneous)

## Homework Equations

I= integral of something :PPP

## The Attempt at a Solution

well i just know that the moment of inertia of a ring of mass M is MR^2/2

seems kinda intuitive,I'd like to know how do I (using integrals) calculate the MoI of a solid sphere as stated above.

Thank you in advance!

Any advice\comment appreciated.
