I believe you propose constant torque drive to the pendulum.in contrast, i suppose that adding mass at v=0 increases amplitude, but adding mass at v = max decreases amplitude. On Friday, July 16, 2021, 06:36:30 PM CDT, bernard cleyet <bernard@cleyet.org> wrote:

If my derivation is correct W/O confounding approximations, adding mass to a driven pendulum causes a decrease in amplitude.  Horologists have long known that adding mass does not increase the Q, at least in their experience.  More correctly, that is, if I’m correct, it at least decreases the amplitude, the opposite of what an increase in Q would cause.

So am I “all wet”? 

bc …  too often naive.  And requests at the suggestion of Antti S.
