John Szmyd FYSE 1214 Space, Time and Measurement Professor Noah Graham 9/25/2007 Oscillators Mass on a Spring : A mass connected to a spring oscillates and can be used as a timekeeping device because of the machine’s elastic properties. The weight provides the inertia, and when the spring attempts to return to an equilibrium it overcompensates, continuing the oscillation. Gravity determines the equilibrium, and the elasticity of the spring provides the restoring force. The period varies with size and weight of spring, ranging from split-seconds to many minutes. Tuning Fork : A tuning fork uses the physical vibrations, not the sound, to move a connected machine at a consistent rate. The inertia is the thickness of the prongs, while the restoring force is the rigidity of the metal. The frequency varies in the hundreds cycles per second range, depending on the length and thickness of the fork (77). The amplitude of the sound does not affect the frequency. Quartz Crystal
