Balance wheel
A balance wheel rocks between its banking pins, the hairspring inside it winding and unwinding with every beat.

Two markers circle one ring at three to one, meeting only at the top and the bottom, where the ring flares on the beat.
Two matched pendulums on one beam keep step through four swings while the amplitude walks from the left one to the right and back.
A decaying sinusoid prints left to right between its dashed decay envelopes, rests fully drawn, then clears and runs again.
A drive slides on its rail and the loaded follower below tracks it at the same period but a sixth of a cycle behind.
A mass runs on its spring while two columns trade the same total between them, kinetic full at the middle and potential full at each turn.
An analysis window walks up a chirp trace and back, lighting only the band under test while the caret keeps step on the frequency rule.
Two perpendicular oscillations locked at two to one close into a figure of eight, with an accent arc walking the curve once per cycle.
A coil stretches and compresses from its fixed top, carrying the mass through its equilibrium line while the needle on the rule reads the displacement.
A bob swings one full period along its arc, hanging a moment at each extreme before falling back through plumb.
One trace holds while the accent copy slides a half wavelength either side of it, the caret on the phase rule reading the same shift.
A drive-frequency cursor sweeps the band and back while its marker rides the response curve, spiking as it crosses the natural frequency.
A crank pin turns at a steady rate and its height is carried across by the projection line to trace the sine beside it.
The third mode on a string fixed at both ends: the antinodes swell through flat and back out while the marked nodes never move.
A disc hung on a wire winds one way, unwinds through zero and winds the other, the caret on the rule reading the twist.
