A Elasticidade Relativista
Abstract
The purpose of this paper is to make clear the difference between rigid and undeformable bodies in Relativity. The error of confusing these two concepts has survived up to the present day treatises. We hope it will not persist in the XXI century treatises. The large majority of relativists do not know the formulae for the relativistic elasticity of rigid bodies (Mc Crea 1952,Brotas 1968). The paradoxes of the rotating disk and of the 3-degrees of freedom of rigidies bodies in Relativity are in the domain of relativistic elasticity.
