摘要
If its radius of gyration is properly tuned, a mass attached to a simple helical spring is able to perform longitudinal and torsional oscillations that are coupled with one another and exhibit the beats characteristic to coupled oscillations. The mechanism of coupling as well as the corresponding differential equations are derived. For the case of resonance, the solutions are compared with experimental results.
