Clocks

frank m asked:

Am seriously interested in purchasing a torsional pendulum clock – must have all parts and the dome in good condition. And must have the winding key.
I am a watch enthusiast and would like to study the working of this clock. It doesn’t matter if the clock isn’t working but must be in a repairable condition. Please let me know if you are interested or let a friend who has such a clolck and willing to sell know, Thanks !!!

By the way for those not familiar this type of clock has a rotational rather than a swinging pendulum. The pendulum hangs on a fine suspension wire.

I’ve got a wind-up pendulum clock (says “Regulator” on the glass) that doesn’t keep the right time. You can adjust the bob’s distance by turning a nut. Does anyone know how to precisely synchronize these things or point me to instructions? There has to be a better way than trial-and-error.
The length measured from what two points? Center of mass to the axis if rotation?

A pendulum clock can be approximated as a simple pendulum of length 1.00m and keeps accurate time at a location where g=9.83 m/s squared. In a location where g=9.78 m/s squared, what must be the new length of the pendulum,such that the clock continues to keep accurate time(that is,its period remains the same)?

I tried using this formula L= Tsquaredg/4pisquared, but im not receiving the right answer…

It chimes on the hour but the number of chimes doesn’t relate to the hour at hand.
