✦ Synopsis

In introducing the subject, the author first describes fundamentals, giving briefly theories. Thereafter is an agreeable blending of theory and practical applications. Under the heading of natural frequency calculations it dwells on such subiects as characteristics of direct coupled electric generating sets to internal combustion engines and marine oil engine installations. Equivalent oscillating systems and determination of stresses due to torsional vibration at nonresonant and resonant speeds are treated in detail. The measurement of torsional vibration amplitudes and stresses is a part of the book that is very interesting. In it is explained the Geiger torsiograph, the D.V.L. torsiograph and others, their operation and how to use the records obtained.

Of similar interest is the treatment on torsional vibration damping devices wherein actual cases are illustrated with various dampers. An appendix gives a method of obtaining the first twelve harmonic components of any periodic function, which should prove quite handy. The index in the back is quite detailed and adds much to the book's practicability.

It is difficult to do complete justice in reviewing this book in emphasizing its usefulness. While the general subject is somewhat specialized its scope is comprehensive. The manner of presentation of the material is admirable. As a text and reference book it is excellent. R. H. OPPERMANN.
