    How Do Bicycle Wheels Interact with Earth's Rotation at the North Pole?

    Thanks again, if only for forcing me to clarify what it is I don't know that I don't know. Apart from my longitudes and latitudes, I have a basic query. So we've established that a horizontal spinning bicycle wheel with its axis extending from the Earths' axis has only its weight to...

    How Do Bicycle Wheels Interact with Earth's Rotation at the North Pole?

    Thanx for the replies.. OK, so levitation is out, no escaping the scales of injustice, question is, will there be any untoward force on the bearings. I'm holding it horizontal so I expect thrust at the base to counter gravity but in a perfect world I imagine I would have no horizontal...

    How Do Bicycle Wheels Interact with Earth's Rotation at the North Pole?

    Hi You'all, Newbie here so no calculus or polysyllabics on the first date please. If I hold a bicycle wheel horizontally and spin it at the north pole, the torque from the Earth spinning and the torque from the bicycle wheel are along the same axis. Does this mean the wheel could float off...
