Stability in aviation : an introduction to dynamical stability as applied to the motions of aeroplanes (1911)
Bryan, George Hartley, 1864-1928 · London : Macmillan · leaf 70
with what one w^ould naturally expect from analogy with the case of a pendulum whose oscilla- tions depend essentially on the height of the point of suspension above the centre of gravity, or again from the case of an aerostat. It must, however, be remembered that the principle is based on the… … Fig. 10. Fig. 8. In the pendulum (Fig. 8), the point of suspension C is fixed so that the pendulum can only turn about C. In this case rotation about G is set up by the moment of the tangential force F acting at C at right angles to GC. In the aerostat (Fig. 9), the hydrostatic thrust IF', equal to…
