Supplementary kit for the rotating system on air bed U8405680 for investigating frictionless rotational motion and oscillations using a large rotating disc. On the underside of the large disc is an angle grid that can be used to provide triggers to a U8533380 laser reflection sensor if the rotation is to be recorded with the help of the 3B NETlog™ interface unit. Typical oscillation periods: 20 s approx. to 2 mins approx. Moment of inertia of large disc: 2.2 g m˛ approx. Contents: 1 Large disc with protractor scale, 350 mm 1 Scaffold stand 1 Cross sleeve 1 Set of coupling springs with magnet (1 N, 2 N, 5 N)
