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.
