  • Detailed decription

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:
  • 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.
