Consirer a rod rotating about one of its extremes such that the other extreme rotates at lightspeed. The centrifugal force at this extreme is(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

F \propto M \omega c

[/tex]

where M is the rest mass and w the angular speed. If the rod were a flexible one we should call it a string, it could vibrate around to keep the stress constant, and this stress (the string tension) should be equal to the Force above, so I wonder if the above formula apears also in strings.

If it does, then the string tension imposes a relationship

[tex]

\omega \propto M^{-1}

[/tex]

Does it?
