Solving for tension of wire that is stretched corresponding to specific frequency.

  1. Apr 29, 2009 #1
    1. The problem statement, all variables and given/known data
    A steel wire in a piano has a length of 56.8 cm and a mass of 5.0 g. To what
    tension must this wire be stretched in order that the fundamental vibration
    correspond to the note of middle C (f = 261.6 Hz)?


    2. Relevant equations
    u*(f2L)^2 = F




    3. The attempt at a solution
    (5g)*(261.6Hz*2*.568m)^2= F
    =441572.63?

    I'm not sure if that's the right equation or if I substituted my values correctly.

    First thing to do is check your units.
