For just that reason this formula does not apply to piano hammers as they are not being CONVERTED into energy - as if they were there wouldn't be a hammer left. It does apply to things such as nuclear reactions, explosions, and the likes. Sunday ramblings............. >> << Brian H. said.."PS, Jim's formula: E = mc2 (energy = mass x speed of light2) would have little to do with the breaking string problem methinks - BH. ">> John, Brian H.; What I said was: "The short answer is yes. The long answer is yes, *explained* by E=MC(squared) :-)" As there are only two known ultimate meaures of speed i.e. 'zero' and the 'speed of light' all speeds are 'realtive' to those two.............besides this formula explains what happens when a nuclear reaction takes place.. IT BREAKS THINGS!!!.. and we are talking about 'broken' strings..Huh??? :-)))) An aside, though related, question(s)...do piano strings break without heat? if so, how? and if not, where did that heat come from or go to? do wool fibers break without heat? if so, how? if not, where did that heat come from or go to? Ammunition for argumetation that I will not use: <<"Einstein mass-energy relation E = mc2, where E is the energy and m the relativistic mass.">> <<"According to the special theory of RELATIVITY, mass increases with speed according to the formula m = m0/÷(1-v2/c2), where m0 is the rest mass (mass at zero velocity) of the body, v its speed, and c the speed of light in vacuum.">> {note that should have a square root sign but I don't know where it is on the keyboard} And I think Brian Trout is correct when he says: "In this formula, it is demonstrated that an increase in mass will also bring about an increase in energy if the formula is to remain valid. Any change on one side of the "=" sign would also need to be reflected on the other side of the "=" sign to maintain the ratio implied." And as Einstein would have said, probably, "the relativeness of these formulae to breaking piano strings is relative to the understanding of relationships within relativity" Of course we would not have understood that right away so I will retract my simile of E=MC2 and say instead....... that a heavier hammer struck with a measurable force will break more strings than will a lighter hammer struck with the same force................but I don't care......... we are going to the Sugar Bowl to play Virginia Tech anyway!!!!!!!!!!!!! :-))))) Jim Bryant (FL)
