Checking the amplitude of a vibrating screen
One of the most important things to check on a periodic basis is the shape of the screen's vibratory motion. In Figure 1, one can see and verify the shape of the vibratory motion: circular (A), elliptical (B) or even …

Types of Vibration: Free, Forced, and Damped Vibration [PDF]
These vibrations occur when a machine is started in motion with no initial input and allowed to vibrate freely. The machine vibrates at one or more natural frequencies before becoming stable. The resolution of free vibration is usually approximately sinusoidal. The amplitude appears to decrease with time. Examples of Free Vibration:

Amplitude | Definition & Facts | Britannica
decay time. amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other.

Anti-vibration obsession
Mr. Lin. Lunatic Member. Nov 29, 2009. #3. Vibrations can pollute the audio signal in a number of ways, so it's something we'd like to minimize everywhere, not just with amplifiers. This seems to be even more the case with tube audio than solid state, since tubes can be microphonic and highly sensitive to any noise/vibrations.
