How can spinning balls close a throttle?

The arms swing outward as speed rises. Their geometry lifts a sliding sleeve, which closes the throttle through a real linkage. This ideal equilibrium lesson shows the direction of feedback rather than simulating engine regulation.

h = g/ω² · closure = 1−h/L

What this model simplifies

Unloaded ideal Watt governor, gravity/centripetal balance. Numerical arms meet on the spindle axis; the illustrated hinge seats are separated for inspection. Pivot offset and sleeve weight are omitted from the readings. Arm stop 75°. No transient or spring-loaded-governor performance claim.
