<DIV style="FONT: 10pt arial"><B>Subject:</B> Math/Physics Problem: degrees of
rotation of tuning pin = how muchpitch change</DIV>
<DIV><BR></DIV>Ok, I asked this on a previous thread, but I think the question
got buried.<BR>How would one calculate the pitch change implied by a given
degree of rotation of a tuning pin?<BR><BR>The know factors would be:
<BR><BR>string length <BR>string thickness<BR>tuning pin diameter (and
therefore radius) <BR><BR>With those factors known, is it possible to
calculate the exact rotational movement (in fractions of a degree)<BR>required
to make a pitch change of say, 1 hertz at the note middle C?<BR><BR>(this is a
impractical theoretical calculation- ignoring, for the moment, and factor of
friction)<BR><BR>Anyone out there better at math than
me?<BR><BR><BR>[kurt]<BR><BR></BLOCKQUOTE></BODY></HTML>
