Book Description

Excerpt from Dynamo Laboratory Manual, for Colleges and Technical Schools This advance edition of our dynamo laboratory manual covers direct-current studies and tests in three sets of experiments. The object of arranging the experiments in sets is to facilitate the use of the manual by students of different grades, that is, by students who devote but a short time to dynamo laboratory work and by students who devote a longer time to this subject. It is difficult to distinguish sharply between pedagogy and practice in a laboratory manual of this kind. It may therefore not be out of order to state that experiments I, 2, 3, 5, 6, 7, 14, 20, 25 and 26 are arranged with reference, primarily to their educational value, whereas the remaining experiments are such as are sometimes carried out in practice. The complete edition of this laboratory manual will include alternating-current studies and tests and it will be ready in June, 1907. The authors believe, from their long experience, that it is necessary to give complete practical directions, written or oral, for the performance of dynamo laboratory work. Completeness of practical directions has, however, an undoubted evil influence in eliminating almost wholly the incentive to originality on the part of the student, and in order to minimize this evil influence, the authors suggest: (a) That students using this manual be thrown almost wholly upon their own resources in the performance of their experimental work, and (b) that great stress be laid by the instructor upon that part of the written report which is devoted to a dicussion of results.
