Physics/Tension belts


My 3D printer may require I adjust the tension of the tension belts to fix axis shifting. The printer makers seem to want people to play it by touch. I was wondering if there is an instrument  for checking tension on a rubber belt?

Most belts which require tightening like this are for much larger and more powerful motors, like cars.  Just google "tension gauge" and you'll turn up dozens of products...but all for much larger systems.  For smaller systems, I'd recommend doing it by hand.  The human sense of touch is surprisingly accurate.  However, Grainger sells a range of them, and they usually have a local warehouse (gigantic corporation) nearby that can ship immediately.  I recall ordering a compressor when I lived in Odessa (Texas, not  Ukraine) and getting it on my doorstep by the time I got home from work that same day.

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.


I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
