Governing Equations

Moment of Inertia
I = 0.5 * m * r²
Spin Velocity
ω = (RPM * 2 * π) / 60
Gyroscopic Torque
T = I * ω * ω_p
Vector cross-product
T_vector = ω_vector × (I * ω_spin_vector)

Gyroscopic torque is directly proportional to the moment of inertia, the spin velocity, and the precession rate.

The reactive torque vector always acts perpendicular to both the spin axis and the precession axis.
