"Oscillation"?
Okay:
Oscillation
Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. The term 'vibration' is precisely used to describe mechanical oscillation but used as a synonym of 'oscillation' too. .......
Sorry Cap, it
is a vibration. Plenty of support provided from engineering sources.
Had he left out the "not vibes", it would have been 'correct". It is indeed vibration, as I originally said, regardless the source.
Glowgeek was quite accurate referring to "vibration", as I also replied, the vibration is made up from several, not a single force.
"Torsional vibrations"
