Web视频字幕. we've learned that axial precession it doesn't change it's not a change in the tilt or the obliquity of our rotational axis it's a change in the direction and over a long period of time 26,000 years it kind of traces out a circle and the main effect of that is that if we wait long enough that our rotational axis or you could say ... 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.

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).
