Gravity applies a torque, but a fast-spinning disk responds by precessing sideways instead of toppling. Faster spin → slower precession: Ω = mgr / (Iω).

▶ Run in Python

Data Inspector

Precession rate Ω15.70 rad/s

Precession period0.4 s

Spin inertia I6.25e-4 kg·m²

Governing equation

Ω = \frac{m g r}{I ω} = \frac{0.5 \cdot 9.81 \cdot 0.08}{I \cdot 40} = 15.70 rad/s

Reading this result: Gravity's torque never tips the top; it steers the spin axis in a circle every 0.4 s, the hallmark of gyroscopic precession.
