2. Melde's experiment - Wikipedia

   en.wikipedia.org/wiki/Melde's_experiment

   A model of Melde's experiment: an electric vibrator connected to a cable drives a pulley that suspends a mass that causes tension in the cable. Melde's experiment is a scientific experiment carried out in 1859 by the German physicist Franz Melde on the standing waves produced in a tense cable originally set oscillating by a tuning fork , later ...

4. Euler's Disk - Wikipedia

   en.wikipedia.org/wiki/Euler's_Disk

   The quest to achieve longer and longer spin times led him to invite MIT professor Peter Fisher onto the show to experiment with the problem. Spinning the ring in a vacuum had no identifiable effect, while a Teflon spinning support surface gave a record time of 51 seconds, corroborating the claim that rolling friction is the primary mechanism ...

5. Foucault pendulum - Wikipedia

   en.wikipedia.org/wiki/Foucault_pendulum

   The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change ...

6. Vibration - Wikipedia

   en.wikipedia.org/wiki/Vibration

   Vibration (from Latin vibrāre 'to shake') is a mechanical phenomenon whereby oscillations occur about an equilibrium point.Vibration may be deterministic if the oscillations can be characterised precisely (e.g. the periodic motion of a pendulum), or random if the oscillations can only be analysed statistically (e.g. the movement of a tire on a gravel road).

7. Vibrator (electronic) - Wikipedia

   en.wikipedia.org/wiki/Vibrator_(electronic)

   Since vibrators were typically plugged into sockets mounted directly on the radio chassis, the vibration could potentially be mechanically coupled to the chassis, causing it to act as a sounding-board for the noise. To prevent this, the sound-deadening lining inside the can was sometimes made thick enough to support the vibrator's components by ...
