Piano wire tensile strength

[V T]

Hi Del,

If this is actually works, I doubt that it has
anything to do with metallurgy.  The only thing that I
can think of is that a twisted wire has some force
vectors that are not aligned with the axis of the
wire.  This may reduce the axial component of the
tension.  In essence, you would get up to the required
pitch with a smaller axial force vector, so it would
appear that the wire can be stretched further before
it breaks.  Plausible???

Best regards,

Vladan
