SUMMARY

This discussion focuses on calculating the precession force acting on an arm in a system involving a rotating wheel, specifically referencing the Anti-Gravity Wheel concept from Veritassium. The parameters defined include the mass of the wheel (Mwheel), the radius of the wheel (Rwheel), and the rotational speed in RPM (Vwheel). The angles between the shaft and arm, as well as the shaft and wheel, are both set at 90 degrees. The length of the shaft (Lshaft) is also considered, although the mass of the shaft is deemed negligible for this calculation.

PREREQUISITES
  • Understanding of rotational dynamics
  • Familiarity with precession in gyroscopic systems
  • Knowledge of basic physics concepts such as mass and angular velocity
  • Ability to interpret physical parameters in mechanical systems
NEXT STEPS
  • Research the equations governing gyroscopic precession
  • Learn about the effects of angular momentum on rotating bodies
  • Explore the principles of torque in relation to rotating systems
  • Investigate the implications of mass distribution on precession
USEFUL FOR

Physics students, mechanical engineers, and hobbyists interested in rotational mechanics and gyroscopic systems will benefit from this discussion.

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.
