Motorised Gyroscope Apparatus
Product Code : EL-TOML-11020
Quick answer: The motorised gyroscope apparatus is used to verify the gyroscopic couple relation by measuring precession under an applied torque. A 250 mm motor-driven rotor, free about the spin, precession and couple axes, is loaded with 0.2, 0.5 or 1 kg weights while a stopwatch times the precession. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the gyroscope experiment is done
A spinning rotor has angular momentum I x omega along its spin axis. When a torque is applied about a second axis, the spin axis does not simply tip over; it turns steadily about a third axis at right angles to both. This turning is precession, and the relation between the three is the gyroscopic couple, C = I x omega x omega_p, where omega_p is the rate of precession.
On the apparatus, hanging a weight at a known distance from the centre gives the applied couple, C = W x L. Timing the rotor frame through a known angle of precession gives omega_p, and the spin speed gives omega. Comparing the applied couple with I x omega x omega_p verifies the relation, the same effect that acts on ship stabilisers, turning aircraft and vehicle wheels on curves.
- Level the frame so that the rotor is balanced with no weight applied.
- Start the motor and set the spin speed with the dimmerstat.
- Hang a 0.2, 0.5 or 1 kg weight at the set distance from the centre.
- Time the precession through a known angle with the stopwatch.
- Repeat for other weights and speeds and compare the applied and calculated couples.
