Gyrostat [noun]

In the theoretical discussion of the general motion General motion of a gyrostat rolling on a plane.

What's the matter with my home-made gyrostat and anemometer?

But now remove the gyrostat from the frame, and set the wheel in rotation.

There is, however, a great difference between the earth and the gyrostat.

Look, for example, at this well-balanced gyrostat (Fig. 17).

Here is a gyrostat (Fig. 23) something like the earth in shape, and it is at rest.

The first phenomenon is most easily studied in this balanced gyrostat (Fig. 13).

It is not precessing, so you know that the weight W just balances the gyrostat F.

Now close observation will give you a simple rule about the behaviour of a gyrostat.

The gyrostat is now replaced on its pivots in the frame, with its axis vertical, and moved about as it was before.
