A treatise on gyrostatics and rotational motion . weight isnow removed, the flywheel is spun, andthe weight is replaced. It is seen nowthat the wheel and case with the support-in fork turn as a whole about ZZ, anddo so more quickly the larger the weightattached. Again, with a given attached weight it is found that the greaterthe angular speed of the rotor, the slower is the speed of turning about have here illustrations of the gyrostatic equation which holds in allthese cases, ( Wiu)= L, where at is the angular speed about the axis ZZ, and Lthe moment of the couple about YY. By the turning about ZZ with speedw angular momentum is being produced about YY at rate Cnco, and thismust be equal to L, the moment of the couple produced about YY by theattached weight. Again, when the weight is attached let a couple be applied by hand inthe direction which seems the natural one to hurry the turning motionabout ZZ. It is Pound that the gyrostat now turns about YY, so as torai8( the weight. On the other hand, if the couple is applied SO as. Motor-gyrostat in pedestal, with weightattached. 28 GYROSTATICS CHAP.
