Summary[edit]
| Description |
English: A bicycle is assembled upside down to model another bike (without trail) driving forward to observe angular momentum forces. The video (same as in File:Bicycle precession experiment, tilted bike.ogg) is rotated. When it's steered at the handlebars (blue axis), the bike gets tilted (red axis). The first movement at 0:15 is modelling a right turn. The video-wheel leans backward as a reaction. For the modeled bike (normal position, drawn grey in the intro) this is a tilting to the left side.
Deutsch: Ein Fahrrad ist so montiert, dass man es pendeln kann. Das Video ist rotiert. Die Drehung der Lenkung wird im Video durch das Pendeln simuliert. Wird also die Lenkstange gedreht (um die blaue Achse), kippt das Rad (um die rote Achse). Die erste Bewegung bei 0:15 simuliert eine Rechtkurve, das Rad im Video kippt nach hinten, für das simulierte Fahrrad (stehend, grau in der Zeichnung am Anfang) ist das das Kippen nach links. |
