Measuring Vibration - Page 6

Measuring Vibration - Page 6. The Difference Between RMS, Peak and Peak to Peak Amplitudes. The "RMS" value is calculated by simply multiplying the peak amplitude (shown in the graphic below) by 0.707: RMS = Peak x 0.707. But is that technically correct ? Technically, the RMS value of a pure sinusoid is equal to the area under the half-wave.
