Homework Help: physics

Posted by Bruce on Friday, July 20, 2012 at 10:32am.

A uniform brass disk of radius R and mass M with a moment of inertia I about its cylindrical axis of symmetry is at a temperature T = 45 C. Determine the fractional change in its moment of inertia if it is heated to a temperature of 125 C. (The linear expansion coefficient for brass is 1.90 10-5 C−1.)

I tried finding the change in volume and using that ratio, but it isn't correct. Im not sure what the best approach is. Thank you for any suggestions!
