Gyroscopic Precession

Interact with parameters governing gyroscopic precession. Adjust rotor mass, radius, speed, and shaft leverage to witness how torque and angular momentum govern the precession rate.

Governing Equations

Moment of Inertia
I = 0.5 * m * R²
Angular Momentum
L = I * ω
Gravitational Torque
τ = m * g * r
Precession Rate
Ω_p = τ / L = (m * g * r) / (I * ω)

Higher spin speeds (ω) increase angular momentum (L), which stabilizes the gyroscope and reduces the precession rate.

Increasing shaft length (r) increases gravity torque, resulting in faster precession.
