Rms vibration

A body is said to vibrate when it describes an oscillating motion about a reference position. The number of times a complete motion cycle takes place during the period of a second is called the frequency and is measured in hertz (Hz). The motion can consist of a single component occurring at a single frequency, as … See more In practice, it is very difficult to avoid vibration.
