18Mechanical vibration
Cause an object to oscillate or vibrate.• Electric carving knife with vibrating blades
Increase its frequency (even up to the ultrasonic).
• Distribute powder with vibration.
Use an object's resonant frequency.
• Destroy gall stones or kidney stones using ultrasonic resonance.
Use piezoelectric vibrators instead of mechanical ones.
• Quartz crystal oscillations drive high accuracy clocks.
Use combined ultrasonic and electromagnetic field oscillations.
• Mixing alloys in an induction furnace
