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.
