Gyroscope coupling force force question

  1. Mar 10, 2012 #1
    Hello everyone,

    I saw this video in youtube:
    And I have some questions, can someone please explain me the forces acting on this gyro? what is the momentum that keeps the cheese from falling, the direction of its action dont add up to me

    Also, how could i calculate the force needed to take down the cheese to the ground given that the RPM is constant (electric motor), unlike in the video above?

    i tried using the following website after reading about gyros:
    http://www.gyroscopes.org/math.asp
    what i dont understand is the omega part, it seems to be zero in the youtube video so how come the coupling force is so big?

    Thanks a lot,
    sharon
