Math/Physics Problem: degrees of rotation of tuning pin = how muchpitch change

[John Ross]

I would wonder, why, with all the variables, would you be interested?
It can obviously be done, but to what end?

  Ok, I asked this on a previous thread, but I think the question got buried.
  How would one calculate the pitch change implied by a given degree of rotation of a tuning pin?

  The know factors would be: 

  string length 
  string thickness
  tuning pin diameter (and therefore radius) 

  With those factors known, is it possible to calculate the exact rotational movement (in fractions of a degree)
  required to make a pitch change of say, 1 hertz at the note middle C?

  (this is a impractical theoretical calculation- ignoring, for the moment, and factor of friction)

  Anyone out there better at math than me?
