Møller radius

  1. Sep 19, 2014 #1
    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!

    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 and p=mv. The two results are identical, but from the references I can find Møller's formula is supposedly fully relativistic...

    anyone? I wouldve expected this to be a quick answer.. To bad I posted this seconds before they shut the site down for migration >.<

    C. Moller, Commun. Dublin Inst. Adv. Stud., A5, 1 (1949).
    C. Moller, ”The Theory of Relativity”, 2nd ed. (Oxford University Press, 1972), p. 176.

    The second (textbook) reference will probably be easier to find. The secondary source for these references was http://www.phys.lsu.edu/faculty/oconnell/PDFfiles/311. Rotation and Spin in Physics.pdf in the section quoted below.

    Thanks pervect, I did come across Moller's stuff but I don't have access through my school (they're too old). I'll check out that second source tho

    >.< yea your source is just like all the ones I found! They reference Moller's work but only show the conclusion...

    Sorry, let me clarify that a little:

    I already have plenty of textbooks on relativity, so buying a new one just for this question seems ridiculous. If there really is no accessible derivation can somebody who has the textbook just sketch the argument out for me?
