QUE SIGNIFIE WHEEL AND AXLE EN ANGLAIS
Roue et l'essieu
La roue et l'essieu sont l'une des six machines simples identifiées par les scientifiques de la Renaissance tirés des textes grecs sur la technologie. La roue et l'essieu sont généralement considérés comme une roue attachée à un essieu de telle sorte que ces deux parties tournent ensemble dans lesquelles une force est transférée de l'une à l'autre. Dans cette configuration, une charnière ou un palier supporte la rotation de l'essieu. Hero of Alexandria a identifié la roue et l'essieu comme l'une des cinq machines simples utilisées pour soulever des poids. On pense que cela a été sous la forme du guindeau qui se compose d'une manivelle ou d'une poulie reliée à un cylindre cylindrique qui procure un avantage mécanique pour enrouler une corde et soulever une charge telle qu'un godet d'un puits. Ce système est une version du levier avec des charges appliquées tangentiellement aux périmètres de la roue et de l'essieu, respectivement, qui sont équilibrés autour de la charnière, qui est le point d'appui. L'avantage mécanique de la roue et de l'essieu est le rapport entre les distances entre le point d'appui et les charges appliquées, ou ce qui correspond au rapport des dimensions radiales de la roue et de l'essieu.
