Movable rotary mass model for demonstrating angular momentum

摘要

The model is operated externally by means of cable pulleys and thrust pistons. Any number of centrifugal masses running along ducts are pulled into the centre by means of cables. The model has a speed counter and dynamometer at the pressure peak. The centrifugal masses are fixed to a swivel arm and are pulled into the centre by cable or by a system of rods.
