Assume a solid disc of such a radius that at 1 rpm, a point on the outermost edge would travel at an angular velocity of 0.9c (or any relativistic speed).
Further assume that it's made of such a material that it doesn't break in any way under the strain.
What, if any, are the relativistic effects of a solid body where there's some portion that's at zero relative speed to the other portion of the body?
