Excerpt from A Handbook of Testing: Materials All technical colleges, and many of the large engineering works, now possess a laboratory furnished with apparatus for the testing of materials. It is hoped that some portion of this book may be of service to engineers engaged in practice, it is, however, written primarily for the college student, although a great engineer has said that one of the attractions of our work is that we are always students in engineering. If, at times, the reader thinks that the descriptions of apparatus, or of tests, are somewhat detailed, he should remember that, although he may be quite familiar with a machine or process, other readers, possibly, have not had the same opportunities. The chief object of the author has been to interest engineers in experimental work. The experience gained in four colleges, and a works testing department, has led to the belief that the great importance of experimental work is not sufficiently recognised. It is hoped that students may be stimulated to look up, both before and after they have made experiments, the description of the apparatus and tests mentioned. The diagrams will perhaps be useful for sketching purposes. The methods of teaching engineering vary in the different centres. No attempt is made in this book to standardise such methods - each instructor is the best judge of what suits the plant and the students. A list of experiments is given in Chapter XII., as it may be useful to those who are commencing to organise a laboratory course. The illustrations have been made especially for the book. Attention has been given to the scheming, as well as the actual drawing and reproduction of diagrams, in the hope that the details of the apparatus described may be made clear. An effort has been made to avoid catalogue illustrations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
