TM 150.02: Free and Damped Torsional Vibrations

Print Ask to this Articlel

Free and Damped Torsional Vibrations

Product Details

Technical Description 
The experimental set includes three different torsion bars and two different mass discs. An oil damper makes it possible to reduce the amplitude. The components are straightforwardly and accurately placed in slots of the frame on the universal vibration system TM 150.

Learning Objectives / Experiments

- Natural frequency of torsional vibration
- Effect of torsional stiffness, rotating mass and damping

* Effect of rotating mass, torsional rigidity and damping
  factor on the behaviour of a rotary oscillator


[1] Supplementary experiment to the universal vibration system TM 150
