Amplitude Definition of Amplitude by Merriam WebsterVibration Introduction OSH Answers

Amplitude definition is the extent or range of a quality property process or phenomenon such as How to use amplitude in a sentence Most light sources produce a mixture of waves with all different physical properties such as wavelength and amplitude of vibrationThe risk of vibration induced injury depends on the average daily exposure An evaluation of the risk takes into account the intensity and frequency of the vibration the duration years of exposure and the part of the body which receives the vibration energy Hand arm vibration

Vibration WikipediaPower Line Aeolian Vibrations ULiege

Vibration testing is accomplished by introducing a forcing function into a structure usually with some type of shaker Alternately a DUT device under test is attached to the table of a shaker Vibration testing is performed to examine the response of a device under test DUT to a defined vibration definition of the maximum vibration amplitudes undergone by the conductor due to aeolian vibrations the steady state amplitude of vibration of the conductor or bundle due to aeolian vibration is that for which the energy dissipated by the conductor and other devices used for its support and protection equals the energy input from the wind
