PURPOSE: TO show that a mechanical oscillator responds with a maximum amplitude to its own resonant frequency.
DESCRIPTION: Three saw blades of different lengths have been rigidly attached to a manual shaker. Shaking the assembly, one can find the resonant frequency of each saw blade.
SUGGESTIONS: Practice.
REFERENCES: (PIRA unavailable.)
EQUIPMENT: Mounted saw blades, rods and clamps, as photographed.
SETUP TIME: None.
