Well, Ron, this presumes a pretty sharp "terminating pivot" which is neither desirable nor even attainable by makers who might think it desirable. The length of wire in contact with the bridge at B is very rarely short enough to qualify as a "pivot" and, whatever the length is, it is pressed firmly against the bridge with a pressure of say 30 lbs. and quite unable to perform any serious dancing. The greater the angle, the greater this pressure and the more the friction -- and there is no disadvantage if the area of contact is longer since the friction will be the same. I'd need to do some experiments before I could utterly refute your theory, but it seems most unlikely. JD --============_-1206809802==_ma============ An HTML attachment was scrubbed...
