This experiment ended up not being successful. The idea was to build a compact torsion pendulum using tungsten wire as a torsion fiber, the weights were 100 grams each. I machined all the parts including vibration damper platforms, and motor mount. The only thing in the photos I didn’t machine myself was the stainless steel weights, which were on loan from my professor at the time (from his Ph.D. thesis). The motor was going to be used to start the pendulum into motion once all the energy was all unwound from it. That way it would start consistently every time. The enclosure was to keep air currents from kicking it into motion. and a small optical physics grade mirror was strapped to the pendulum body. A laser was bounced off of it and image processing libraries in mathematica were to be used to track the movement of the laser as it passed a central marker on the path of the pendulums motion. In the end, it was too sensitive and technically, even flushing nearby toilets could put energy into it.
