Suppose a rigid body (say a sphere) ofis rotating with angular velocity A. Any point at a distance r from the axis of rotation has tangential velocity v=A*r and that v must be less than c. Does this mean that :(adsbygoogle = window.adsbygoogle || []).push({});

1. The rigid body can only be a certain maximum (radial) size r, where r<A/c?

2. If you try to increase its angular velocity, it will no longer stay rigid?
