This is a multi-part message in MIME format. ---------------------- multipart/mixed attachment (Pleas ignore the last drawing I sent I did not spell check it.) Here is some more on this topic. Think of "I" as the total MOI of the action. Think of "h" as the key dip. "m" would be the force of playing minus the balance weight. It is interesting that the square root of 2gh is the velocity reached at free fall of the mass "m". As you see it can't be reached here. So, no mater how heavy a weight we lay on the key the key can't reach the acceleration a "g" gravity. More later on this.
