Objects in motion relative to an inertial frame S are measured to have contracted lengths in S in the direction of motion. How does Special Relativity view this contraction physically?
For a concrete example, suppose I have a bar of steel moving lengthwise and, as it moves past me (in frame S) I tap it in the center. How do I determine how it will vibrate? (It is shorter than at rest and more massive. Perhaps it's elasticity has changed. etc.?)
