Maybe you are looking up the wrong formula or misunderstand something. I have roughly 10-12 Physics books and they all agree with each other. What book are you using?

Additionally here are 5 URLs showing the Squared factor and NOT the fourth power. Try Google for many many other citations and examples.

The first one shows an attempt to derive the MOi for the various shapes comprising a particular wheel. Hope this helps.


Stan, sorry old chap I will send you the calculation you are right for a rod but do the integral of the moment of innertia for a circle ie sum of M x (r squared) for the limits of a circle and it will all make sense, I'll prove it when I get back from work - Must dash I have a final interview for a job - Fortunately not involving rotational mass calculations !!!
