Re: tribophysics



Haha, do you know what that is? I had to look it up myself.

I am looking for a source of into about triboelectric behavior of
different materials. I recently had some unexpected (but not uncommon,
so I'm told) trouble rubbing wool on a plastic rod. Sometimes the rod
charged up negatively, sometimes positively. It was suggested that the
materials were too close on a 'triboelectric scale.' Well, maybe, maybe
not. Where can I find information like that? It's not in the old
physics books I used in college. Is it engineering info?

Thanks,

Keith

I found this lately from a colleague. Never heard of it before but it does
seem to work, even with friction,
