How does a pendulum divide time into equal beats?
Fit the components before testing.
A small-angle pendulum sets the beat; the escapement releases the train by one tooth each half swing and replenishes frictional losses. Changing pendulum length changes the rate.
Longcase clock with a schematic deadbeat escapement. Small-angle period, g=9.81 m/s²; reference full period 2 s. No temperature, amplitude or exact clock specification.
Tune a seconds pendulum to less than 60 seconds daily error.
Tune pendulum timing with the escapement engaged.
