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

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?
