ANGULAR MOMENTUM COONSERVATION DEMONSTRATION STAND

摘要

The invention concerns an angular momentum conservation demonstration stand designed for school physics and mechanics laboratories. In accordance with this invention, the stand consists of a direct-current engine, which includes a rotor and a fixed coil that revolve around each other or around a fixed mark, and other direct-current engines, which all spin shafts through bearings. The direct current is supplied through several brushes located on the base plate using brackets. Several disks with equidistant holes are located on the above-mentioned shafts. These disks act as a counting device as they pass before photoelectric cells that are mounted in boxes attached to on the base plate through brackets.
