Driven Mechanical Resonance: Torsion Pendulum (Leybold/Pohl's)

PIRA 3A60.55 - Driven Mechanical Resonance: Torsion Pendulum (Leybold/Pohls Torsion Pendulum)

Photos Show the Demo Apparatus Used at the University of Texas at Austin.

Instructions / Notes:

Oscillation system consists of a rotating wheel driven by motor
The larger of the two wheels drives a rod which is connected to a small second wheel.
A torsion spring is mounted to the same axle as the small wheel.
Exciter frequency ranges from 0 to 1.3 Hz
The torsion spring oscillator has a natural frequency that is approximately .5 Hz
This demonstration takes a full minute or two to reach full resonance.
A stop-watch is available by special request.
