While replacing the cambelt on my car at the weekend I noticed yet again a quote for tension in 'seems', this is something that is a recent development, till now I've used nM as a tension setting.
Doing a little research I've found its difficult to convert from seem to anything else, turns out that seem is not a measure of tension, its a frequency, the seem guage somehow 'strums' the belt or makes it resonate, rather like a e-bow sustain device for a guitar, so its resonant freq can be measured.
These things are ridiculously expensive and I was wondering about the possibility of building one, excitation could be from a low freq impulse or maybe like a sustain device a pickup and a transducer with a lot of gian inbetween, making an oscillator with the belt being the resonant section.
Any thoughts?
P.S. I've heard the joke 'seems tight enough' before.
