G1-57: INVERTED PENDULUM - SPEAKER DRIVEN

PURPOSE: To demonstrate the conditions for stability of an inverted pendulum.

DESCRIPTION: A weighted straw hinged at the center of a loudspeaker is used as an inverted pendulum, which is driven by a sinusoidal wave to the speaker. The effect of variation of the driver frequency and amplitude on the stability can be easily studied.

SUGGESTIONS:

REFERENCES: (PIRA 3A60.64) See Demonstration Reference File for information and theory regarding the inverted pendulum.

EQUIPMENT: Loudspeaker inverted pendulum, oscillator and 20 Watt power amplifier.

SETUP TIME: 5 min.
