String tension, is this the correct formula?

  1. Feb 26, 2004 #1
    I read in a book that tension = 1/(pa'), where a' = alpha prime.

    Is this the correct formula for string tension and if so what is p?

    in my book, it is


    [itex]\pi[/itex] is the ratio of the circumference of a circle to its diameter, approximately 3.14. and if your source differs by a factor of 2 from mine, i wouldn't worry about it.

    ah, p must be pi then, would that make sense for a closed string then?
