Excerpt from Machine Design One can never become a machine designer by studying books. Much help may come from books, but the true designer must have judgment, ripened by experience, in. Constructing and operating machines. One may know the laws that govern the development, transmission and application of energy, may have knowledge of constructive materials, may know how to obtain results by mathematical processes, and yet be unable to design a good machine. There is also needed a knowledge of many things connected with manufacture, transportation, erection and operation. With this knowledge it is possible to take results of computation and accept, reject and modify until a machine is produced that will do the required work satisfactorily. Professor John E. Sweet once said, It is comparatively easy to design a good new machine, but it is very hard to design a machine that will be good when it is old. A machine must not only do its work at first, but must continue to do it with a minimum of repairs as long as the work needs to be done. The designer must be able to foresee the results of machine operation, he must have imagination. This is an inborn power, but it may be developed by use and by engineering experience.
