Ever see amplitudes increase drastically at 1x? Did you know
that a strobe light is a great way to inspect for structural looseness, often
the cause of such a sudden increase (literally – something broke)? To do this, we utilize the very same Slow Motion Study
techniques we discussed previously.
By tuning to the frequency of interest and then tuning
slightly away from that, you will be
amazed at some of the things you can see happening on the structure.
Sometimes you need to play a bit with your flash rate but you will find this to
be a useful technique in finding broken welds, loose feet, housing distortion,
loose and broken fasteners and many more causes of abnormally high amplitudes.
This tip is provided by Scott Dow, Senior Instructor of Mobius Institute.
