This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Dear Physicists of the List- Please comment on this thought: When I press the piano key, the resistance to movement I feel consists = of three elements 1) Friction 2) The pull of gravity on the hammer and wippen, partly counterbalanced = by the pull of gravity on the keyfront. 3) The combined MOI's of the various moving parts. Therefore, if I can=20 1) reduce the friction to zero, and=20 2) use a wippen assist spring to produce a balance weight of zero, the = only resistance left would be=20 3) the combined MOI's of the key, wippen and hammer. =20 What I would feel then, in various key strokes, would be whatever it is = we are talking about.=20 Could I make or buy a gauge to measure this?=20 Does this line of thought seem useful in understanding the situation? For example, has anyone felt a key such as I describe? Ed Sutton ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
