PHYS-L, PHYSHARE, and TAP-L, people!
There is a controversy among the horological community on the effect of
pendulum mass on the steady state amplitude of an escapement driven
clock, in particular the impulsing by the gravity arm of a Synchronome
clock. Theoretically for a simple pendulum clock with a decay constant
independent of the mass, there is, obviously, no effect. However, the
free decay (they call it "run down") is, theoretically much effected;
the time is proportional to the mass. I have searched somewhat
diligently and find no data (experimental) relating to this effect. Do
any of you have such?
bc, frustrated.
