Excerpt from Problems in Alternating Current Machinery
These problems chiefly concern the theory of the operation of alternating current machinery, and are such as we give to the fourth year students in electrical engineering in this subject.
In each chapter the problems of a similar nature are grouped together, and those of each group are then arranged in the approximate order of their difficulty. The groups in each chapter follow each other in as logical an order as possible, both from point of difficulty and the presentation of the subject. In order that this collection of problems may be useful among different classes of students a large variety has been included, ranging from the very simple to those of considerable difficulty. Wherever it is essential the data have been taken from actual apparatus. This was possible through the courtesy of two of the large manufacturing companies. In some of the problems so few data are given that approximate methods of solution must be used, but care has been taken to so state them that the errors thus introduced need not be large. This lack of data is frequently met in practice.
It has been thought best not to give introductory paragraphs for each chapter as was done in the preceding volume of problems inasmuch as they would have to be of considerable length to be of much value.
The answers to the problems will probably be ready for publication in the fall of 1914. They will be available to all but undergraduate students at a nominal price. Undergraduate students can obtain them only on the recommendation of their instructors.
