How do you measure mechanical frequency?

Answer 1

I assume you mean measure the frequency of vibration of a mechanical system or part. You use a stroboscope, which is a light that flashes briefly and rapidly. You shine the light on the object and adjust the frequency of the strobe by turning a dial until the object stops moving. You then read the dial to determine the frequency. there are steps you have to take to avoid synchronizing to a subharmonic of the base frequency. For example, if the object is vibrating at 100Hz (10ms), running the strobe at 50hz will also stop the motion, as it will pick up every other cycle.

Answer 2

Mechanical frequency can be measured using a sensor or device specifically designed to detect vibrations or oscillations in a mechanical system. Common methods include using accelerometers, piezoelectric sensors, or laser vibrometers to capture the frequency of the mechanical motion. This frequency is usually expressed in hertz (Hz) or cycles per second.
