Yeah, the one for wound strings would be tough I imagine. It must
be obscure because I don't even know where to look for it.  <ahem> 
  For tough and obscure in the plain wire formula there is  "radius
of gyration about its neutral axis of cross section."   This must
be a constant because McFerrin conveniently gets that as part of 
3.4*10^13, along with PI, the acceleration of gravity , the density
of steel in music wire,  Young's modulus (of elasticity?) for music
wire and the mysterious 1731 ---ric
