Youngs Modulus for Piano wire

[Ric Brekne]

Hi Stéphane and David. 

The two different numbers you give illustrate why I asked to begin 
with.  Davids is from McFerrin, and Stéphane gives from a string 
manufacturer.  I find something fairly close to 210 (kN / (mm^2)) in 
several places... but cant discount McFerrin... even tho thats a bit old. 

    210 (kN / (mm^2)) = 47 209.8781 pounds force / (mm^2)
    2 x (10^7) (pounds / (inches^2)) = 31 000.062 pounds / (mm^2)

Hi Ric.

I think Röslau has 210 kN/mm²

Stéphane Collin.

-------------------
Young's modulus for piano wire is about 2x10^7 lbs/sq.in, or 1.92 x 
10^12 dynes/cm sq.
