How to calculate the precession

  1. May 19, 2015 #1
    This is the Anti gravity wheel video from Veritassium. I have a similar problem to calculate the forces on arm.


    How can I calculate the precession force pushing the arm vertically ?

    Lets assume that the angles between shaft and arm is 90° the angles between shaft and wheel is 90°

    The wheel properties are
    Mass - Mwheel ,
    Radius - Rwheel,
    Speed(rpm) - Vwheel,

    The length of shaft is Lshaft, and mass is Mshaft though to keep it simple we can ignore the mass of shaft. dSuN5.jpg
