Gyroscope & Gimbal Cradle

This is an excellent, inexpensive apparatus for experiments in precession, inertial guidance, and gyroscopic stabilization.

The sturdy gyroscope has a brass rotor, 6 cm in diameter. The rotor is dynamically balanced to within 0.5 g. Its steel shaft has polished bearing surfaces and adjustable teflon bearings that will allow it to run three times as long as gyroscopes with conventional cone bearings. A teacher’s guide describing several experiments is included.
