Man kann Energie nicht erzeugen, nur umwandeln.

Homer S.

Was soll denn das sein, was Du gezeichnet hast? Ein Gewicht (orange) an einem Hebel (schwarz) in Wasser (blau) getaucht?
Wenn dem so w?re, so wird in Wasser -mal abgesehen von Str?mungsverlusten- das Drehmoment entspechend der Gewichtskraft der von Hebel und Gewicht verdr?ngten Fl?ssigkeit kleiner.
