Hi folks I'm looking at how to compensate for use of pure sound wire in spreadsheets for calculating scales. I have the Tension bit figured out, but I am unsure of how to deal with breaking tension and % of that. Roberts gives a simple 0.557*d^1.667 (d in mils) and result in lbs. This is for steel wire with an average density of 7.85 gm /cm^3 and an E modulus of 192 kN/mm2 Pure sound has an average density of 7.87 and an E modulus of 187.5 What I need to know is what the formula for % breaking strength for pure sound is. Any help to get out there ? Cheers RicB
