Low Frequency Resonance Excitation

You are here

RS Low Frequency Vibration Experiment

Hello, All,

Recently I took advantage of a quite Friday afternoon to create an experiment/demonstration of a low frequency resonance being excited on the ESPEC Qualmark RS system.  I took three different lengths of 3/8" all-thread rod and fixtured them parallel to the table top.  I put masses on the ends of the rods to shift the resonant frequencies down.  Take a look at the video to see the results, and feel free to post any comments or questions below. 

Thanks for watching!  And remember - if it isn't broken, you're not done yet!
