Mechanical Resonance

Natural Frequency All objects have a NATURAL FREQUENCY at which they tend to vibrate. This frequency depends on the material the object is made of, the shape, and many other factors.

Mechanical Resonance If a PERIODIC FORCE or vibration has the SAME (or very close to the same) frequency as the NATURAL FREQUENCY of the object, resonance occurs. When resonance occurs the object will begin to vibrate with a VERY LARGE AMPLITUDE.

Mechanical Resonce Approximately equal Forcing Frequency Under these conditions, large amplitude oscillations will occur. Natural Frequency
