Coil spring vibrations
Investigation of vibrations on a spiral spring rotating mass system
Features
- torsional oscillations of a spring-mass system
Learning objectives/experiments
- determine the rigidity of a helical spring
- determine the natural frequency of a spring-mass system
- investigate the effect of mass and mass distribution
