The Gyroscope: Theory and Applications

The aim of this hook is to give a sound, systematic, unmistakably clear and reasonably complete treatment of the mathematical and mechanical aspects of the gyroscope and its more important applications. 
Since the book is concerned with fundamental principles, constructional details are not entered into except insofar as they may aid in clarifying the principles. Friction has been left out of consideration in the motion of the gyroscope itself, because the construction, mounting and casing of modern gyroscopes are such as to keep
friction of all kinds as low as  possible. Unavoidable friction is taken care of by the driving motor.
Because I think the mathematical theory of the gyroscope and its applications are best treated with the aid of vectors, I have used vector methods throughout the book. And since a knowledge of vector analysis is not assumed on the part of the reader, the first chapter is devoted to the exposition of the amount of vector analysis needed in the subsequent chapters.
