If the top is placed on a flat surface near the surface of Earth at an angle to the vertical and is not spinning, it will fall over, due to the force of gravity producing a torque acting on its center of mass. This is shown in Figure 11.20 (a).

WebMay 3, 2024 · by Albert Schödlbauer I saw a picture of precession and nutation of Earth's axis. In German but I suppose it is understandable. The precession is: $$ 360 ^\circ / (25.728 \text{ years}) = 50.2 '' \text{ per year} $$ In the book the autor states that the true rotation axis moves along a small cone wrt the average rotation axis. WebApr 8, 2016 · Explanation: It takes about 258 centuries (Great Year) for one complete precession-rotation of the polar axis about the mean position that is normal to the Earth 's orbital plane (ecliptic). This rate is nearly #360/25800^o=0.01395^o= 5 second/year. WebPrecession is the phenomenon that the axis of rotation changes with time. Tilt describes the angle of the axis of rotation at a given moment in time relative to some reference.
