the period of swing of a simple gravity pendulum depends on its length, the local strength of gravity, and to a small extent on the maximum angle that the pendulum swings away from vertical, "θ", called the amplitude. it is independent of the mass of the bob. the true period "t" of a simple pendulum, the time taken for a complete cycle of an ideal simple gravity pendulum, can be written in several different forms (see pendulum (mathematics) ), one example being the infinite series:
linear approximation
one oscillation of the torsion pendulum usually takes 12, 15, or 20 seconds. the escapement mechanism, that changes the rotational motion of the clock's gears to pulses to drive the torsion pendulum, works rather like an anchor escapement. a crutch device at the top of the torsion spring engages a lever with two anchor-shaped arms; the arms in turn alternately engage the teeth of the escape wheel. as the anchor releases a tooth of the escape wheel, the lever, which is fixed to the anchor, moves to one side and, via the crutch, gives a small twist to the top of the torsion spring. this is just enough to keep the oscillation going.
