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.
