I am not completely convinced that the modern resolution is correct.
Is it? Is anyone aware of any experiments that have been done that relate to this effect? Reference: http://en.wikipedia.org/wiki/Ehrenfest_paradox

Hi, this topic has been well discussed before (and despite some confusion in the literature it never really was a paradox), see:
 http://www.physicsforums.com/showpos...53&postcount=5  The original paper simply proves that according to SR real matter cannot be totally rigid (and there is nothing paradoxical about that): http://en.wikisource.org/wiki/Unifor..._of_Relativity PS. A short answer about experiments: it is very difficult to imagine an experiment that could allow to verify the contraction of a spinning disc. The inertial effect is always much greater and already notsofast rotating discs disintegrate (explode).
