Rotating System on Air Bed
Educational Materials Physics Educational Materials Mechanics Learning Activities
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
Experiment topics:
Rotational motion: uniform and under constant acceleration
Newton's equations of motion for rotational motion
Moment of inertia and torque
Moment of inertia as determined by experiment
Simple harmonic motion of rotating objects
Specifications:
Protractor scale: 0 – 360°
Scale divisions: 1°
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.

The supplementary kit for the rotating system on air bed is 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 laser reflection sensor.
