Problems in Alternating Current Machinery by WALDO v. LYON edited.pdf

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 obta:in them only on the recommendation of their
instructors.
