The waveform from a mechanical vibration is sensed by a velocity-sensitive vibrometer. The oscilloscope trave indicates that the motion is essentially simple harmonic. A 1-kHz oscillator is used for time calibration, and 4 cycles of the vibration are found to correspond to 24 cycles from the oscillator. Calibrated vibrometer output indicates a velocity amplitude (1/2 peak-to-peak) of 3.8 mm/s. Determine (a) the displacement amplitude in mm and (b) the acceleration amplitude in standard g's.
