Abstract:

Several theories have suggested the possibility that the space-time metric of a rotating disk could be nonstatic as well as non-Euclidean. These, and also a theory of optical aberration based on the Thomas precession of vectors, predict a real or apparent decrease in angular velocity with radius, even in an ideally rigid disk, with a rim lag time period of alpha v squaredc squared, where v is rim speed, c is light speed, and alpha is a constant between 1 and 16, depending on the theory. A spinning-disk experiment was done at the Naval Ordnance Laboratory NOL over a four-month period of continuous rotation to look for such effects.
