[attachment=18373]

Most vibrations are undesirable, but there are many instances where vibrations are useful
Ultrasonic (very high frequency) vibrations
Tooth cleaning
Imaging of internal organs
Welding
Vibration conveyers
Time-keeping instruments
Impactors
Music
Heartbeat


Fundamentals of Vibration


Nature of vibration of mechanical systems

Free and forced vibrations

Frequency response functions


Linear Systems


Output frequency = Input frequency

If the magnitude of the excitation is changed, the
response will change by the same amount
