机械工程师的任务
Do you realize that every time you take a step,the bones in your hip are subjected to forces between four and five times your body weight?
你是否意识到，你每走一步路，你臀部的骨骼在承受四五倍于你体重的力量？
When you are running, this force is increased further still.
跑步的时候，这种力量还会更大。
What happens if through disease a hip-joint ceases to be able to resist such forces?
如果因为疾病导致其中一个髋关节不再能够支撑这么多的力量，将会出现什么情形呢？
For many years hip-joints and other body joints have been replaceable either partially or completely.
多年来，人们就已经在部分地或全部地替换身上的髋关节或其他关节。
It is after all a simple ball and socket joint;it has certain loads imposed on it;it needs reliability over a defined life;it must contain materials suitable for the working environment.
毕竟这不过是个简单的球窝接头，它需承受一定的负荷，要求在正常使用寿命内百分之百不出问题，而且必须用适合其工作环境的材料来制作。
Any engineer will recognize these as characteristic of a typical engineering problem,which doctors and engineers have worked together to solve,in order to bring a fresh lease of life to people who would otherwise be disabled.
任何工程师都会把这些要求看做是个典型的工程问题，而这个问题医生和工程师已经合作解决，旨在让原本会残疾的人获得新生。
This typifies the way in which engineers work to help people and create a better quality of life.
工程师可以帮助人们创造更高质量的生活，上面这一点正是他们的工作方法的写照。

Mechanical engineers have worked with farmers and biologists to produce fertilizers, machinery and harvesting systems.
机械工程师与农民，生物学家一起共事，共同生产制造出化肥，机械和收割系统。
This team effort has now produced crops uniformly waist high or less so that they are better suited to mechanical harvesting.
现在这个团队合作生产的农作物一律齐腰高，这样就更适合机器收割。
Similar advances with other crops have released people from hard and boring jobs for more creative work,whilst machines harvest crops more efficiently with less waste.
对其他农作物所做的类似改进使得人们可以从脏活累活中解脱出来，从而转向那些更富有创造性的工作，同时由机器收割庄稼可以提高效率，降低损耗。
