Rotating System in Air Bed
Apparatus for investigating frictionless rotation. A small rotating disc with a protractor scale supports a cross bar to which weights can be attached. The disc is supported by a bed of air in which its axis is centred. A driving weight is suspended from a hook at the end of a string that is passed over a single pulley on one side and a multiple pulley on the other.
The rotation is very slow and can be measured using a stopwatch by hand. Alternatively, a digital timer may be used. This can be started by a mechanism that is supplied with the kit and halted by a signal from a laser reflection sensor when the wheel passes through angle zero.
Protractor scale: 0 - 360 °
Scale divisions: 1 ° < br> Length of cross bar: ca. 440 mm
Radii of perforations: 30 - 210 mm
Separation of perforations: 20 mm
Radii of multiple pulley: 5.0 mm / 10.0 mm / 15.0 mm
Moment of inertia of
disc with cross bar: 0.16 g m2 approx.
Maximum moment of inertia: 7.1 g m2 approx.
Minimum driving torque: 0.05 mN m approx.
Maximum driving torque: 0.60 mN m approx.
