Hello, Khimik, you wrote: K> Here there was video where the antigravity based on gyroscopic effects is shown type: K> video like as all speaks it: no antigravity is present, the effect is based on other load distribution on muscles and on something else: Rotating body hold a hand far from the center of gravity. As a result of it there is the notable rotating moment generated in pair of opposite directional forces: a hand - gravity. This rotating moment is directed on to an axis of a rotating body therefore there is a precession which cyclical frequency can be calculated under simple formulas. Normal gyroscopic effect. Certainly, for lack of rotation, the body behaves absolutely differently. And demonstrators simply do not have force of a paintbrush to create the sufficient rotating moment resulting a body in horizontal position. Thus both of them without special work lift a body over the earth. So to speak about "" in this case it is possible only counting on absolutely the naive spectator [Upd] the Most "surprising" moment, in my opinion, that fact here is that the spin axis by gravity bends not downwards, and is turned sideways. At the same time it easily speaks by means of a mathematical model. The pulse moment can be considered as a vector directed along a spin axis, and proportional angular rotational speed (if to be more exact, angular speeds equal to product at the moment of inertia of a body concerning a spin axis). The same as and to normal forces and pulses, by the moments of forces and pulses we apply the superposition principle: if on a body some moments of forces that the resultant moment of pulse operate will be equal to the total the component moments of pulses. In our case, the axis of a rotating body is allocated horizontally and the vector of its moment coincides with a spin axis and can be directed to one, or in other side, depending on a rotation sense. The pair of forces a hand - gravity creates the pulse moment which vector is allocated also horizontally, but always to the instant spin axis. By a rule of parallelograms the resultant vector also appears allocated horizontally, but slightly rejected sideways. Thus the spin axis too drifts in the same . The moment component , caused in the pair forces a hand - gravity also is continuously turned, therefore as it is always perpendicular the instant spin axis.
