// Präzession eines Schwungrads
//
// Am Schwungrad lassen sich die Auswirkungen der Präzession aufzeigen. Ein Kippen
// der Rotationsachse vom Schwungrad ruft senkrecht zur Achse stehende Kräfte hervor.
// Zentrales Element bildet ein Schwungrad. Damit die vielen Vektoren erkennbar sind,
// wird das als transparentes Objekt abgebilet. Eine Änderung des Drehimpulses führt
// zu entsprechenden Kräften.
// Globale Definitionen
