Constrained Pendulum and Earth Rotation

[John HaineParticipant @johnhaine32865]

This is what I mean.

The plane is XY (which could be the earth's surface near to the pole). The vertical axis is Z, and the plane rotates around Z. The wheel axis in this case is horizontal and parallel to the Y axis. The wheel rotates around this. The vertical axis through the wheel's CG is actually the Z axis, but the wheel is not rotating around it.

I discovered the Coriolis effect as a child, playing on a roundabout. Trying to kick the central pillar whilst facing inwards, my foot was deflected to the left.

Saved from a life of delinquency by the coriolis effect!

Reminds me a of an avatar cartoon I saw recently – Mother to errant child: "Look here young, Copernicus, you'll have to learn the world does not revolve around you."

You mean I'm not a senile delinquent, even after trying so hard for so long? Oh drat! And double drat!!
