Default Re: Rotational Inertia

Damn you really have my brain working on this. I think the inertia is the same between the two though. I don't think that where the weight is located has anything to do with it. I can argue both ways though, this sucks.
I need to find an answer, this is gonna bug me until I do.
The wind-up gyroscopes with the little string keep popping into my head, they have all their rotational mass on the outer diameter, which I'm assuming is to maximize inertia for a given mass at whatever diameter. I'd almost argue the whole case on that point alone. I seem to remember something about inertia and the rotational mass vs. distance from the center of whatever is rotating, like the closer to the center, the less inertia a given mass carries (stores?)..

I'm not a physics student, so don't anyone rip my argument or vocab to shreds, I know it's probably not correct.
