>Mike Spalding >Your comment: "At a given length and frequency, the percentage breaking >strength of the steel wire is constant."!!!!!!!' >I hate to tell you this, but, it's not! >Here is the approximate breaking strengths of piano wire: Joe, Go back to your worksheet and look at the break% column as you change wire sizes on any plain wire unison of given length and frequency. In reality, the smaller sizes do have a little higher tensile strength than the larger, but with the Sanderson formula, the break% for the unison doesn't change with wire size changes. Changing either the frequency, or the speaking length will change the break% calculation in the worksheet, but changing wire size won't. That's what Mike is talking about. Ron N
