Uranus isn't eccentric; its path is almost a perfect circle. Strangely though, Uranus' axis of rotation is almost parallel to the ecliptic plane. Uranus has 27 moons.
If accretion takes place in eccentric orbits as well, the rotation will be prograde and of the right order of magnitude.
如果吸积发生在偏心轨道，则自转将是正向的，且快慢也合适。

The calculation formulas for strength of concrete hinge under concentric and eccentric compressive forces and the method of design considering the rotation of concrete hinge are suggested.
