# Which force acts as centripetal force on gyroscope?

I think I have understood gyroscope in terms of angular momentum and how the torque of gravitational force moves it the way it does.

Also I understand the direction in which it would move: What determines the direction of precession of a gyroscope?

And the working : https://physics.stackexchange.com/a/226485/102169

I saw a couple of videos about it: https://youtu.be/ty9QSiVC2g0

Note how the wheel rotates around. So the Centre of Mass of the wheel goes around the wheel in a horizontal circle. Which force acts on the system of Rod and the Wheel that makes it perform circular motion?

I see it analogous to a particle performing circular motion or a rod being rotated about one of its end (a compound system).

Since the string attached would only pull it up, I understand why it doesn't fall off against gravity but why does it perform circular motion without a centripetal force?

Is anything wrong in my analogy? Or is there a force I don't see?
