Can someone either derive or point me to a derivation of Møller's formula for the relativistic minimum radius of a rotating body? I've been searching for about an hour and it's driving me crazy!(adsbygoogle = window.adsbygoogle || []).push({});

The only "minimum radius" equation I've seen imposes the speed limit c on a classical rotating body (v = L/mR < c). This is only semi-relativistic since it takes L=r x p andp=mv. The two results are identical, but from the references I can find Møller's formula is supposedly fully relativistic...
