Above data suggest, that a favourable ratio of equatorial velocity to escape- velocity is a precondition for formation of planetary ring systems. This ratio (a : b) also seems to determine the mean density and ellipticity of a planet.
Data Source:
NASA  <  http://nssdc.gsfc.nasa.gov/planetary/factsheet/   >  with own calculations.
The rotation period  and  radius of Uranus are not well defined yet. Uranus’  mean density will fall into the apparent pattern, if its radius is being measured at a somewhat different pressure level.


Figure 3/5: Swing System

“Shaker effects” as described in Article 1 and 2 are equivalent to swing effects.

Swing Effects

Swing Effects

A rotation in a swing (grafik) is being driven by lifting one’s body mass against earth’s gravitation. A rotation produced by “shaker effects” is being driven by “lifting” masses against centrifugal forces – as in case of a rotating fluid in an shaken glass. Gravitational forces and centrifugal forces are equivalent, as far as laws of motion are concerned
