飞行器上的某轴，在轮子连接处，按强度要求，直径应为10cm,但如果整个轴都采用直径10cm的钢材，将会增加飞行器的重量，而且除了连接处外，其他地方也不需要如此粗的轴，只需5cm粗就够了。为了解决重量和强度的矛盾，可以将轴做成“纺锤”状，如图2-1.也就是说，这条轴的直径不同部位可以不同，只要连接处的直径达到10cm就行了。
Some axle on the aircraft is in the wheel junction, according to the intensity requirement, the diameter should be 10cm, but if the whole axle adopts the steel of the diameter 10cm, will increase the weight of the aircraft , and besides junction, the other places do not need so thick an axle either, it is thick and enough to only need 5cm. In order to solve the contradictions of the weight and intensity , can make the axle into the " spindle " form , such as Fig. 2-1. That is to say , different position of diameter of this axle can be different , only need reach 10cm in diameter of the junction.
