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。
On flight vehicle some axis, in the wheel attachment point, according to the intensity request, the diameter should be 10cm,But if the entire axis all will use diameter 10cm the steel products, will be able to increase the flight vehicle the weight, moreover besides the attachment point, other places will not need the so thick axis, only needed 5cm thickly to suffice. In order to solve the weight and the intensity contradiction, may make the axis "the spindle" the shape, like chart 2-1.In other words, this axis diameter different spot may be different, so long as the attachment point diameter achieved 10cm was good.
