Excerpt from Electrical Equipment, Its Section and Arrangement: With Special Reference to Factories, Shops and Industrial Plants

A working knowledge of electrical engineering is becoming of greater importance every day as the applications Of electrical apparatus increase. The usual course of instruction given to mechanical engineers includes a discussion of the theory of Opera tion of the various electrical machines but goes no further. It is often said in criticism of college instruction that the student learns more of engineering in the first three months of practice than he does during 'his whole college career. What he really does when he begins his practice is to work on a limited number Of problems, to the solution Of which he has to bring the sum total Of his experience; and thus he gradually gains confidence in himself.

The mechanical engineers at Cornell University cover the usual course on the principles of electrical engineering during their junior year, and it was considered desirable that the work of the senior year include one or two pretentious projects, consist ing of the selection and arrangement Of all the electrical equip ment for an industrial plant, such as a machine shop or a cement plant - problems that require for their solution a comprehensive rather than a detailed knowledge Of electrical apparatus. It was soon found, however, that the student lacked the broad point of view that comes from practice. He knew for example that direct-current motors were good for speed adjustment and that alternating-current motors were essentially constant-speed ma chines, but he was not able to reach the conclusion that there fore direct-current supply was desirable for machine shops with many variable-speed tools.

The set Of notes prepared by Mr. Brown to guide the student in his work contained so__much useful information not to be found in books that it was considered desirable to Offer them to the engineering profession. There are innumerable books for wire men and for the shop mechanic, but there was no book on the market written specially to guide the mechanical engineer in the selection Of his electrical equipment.
