Mechanics of Gyroscopic Systems – Ishlinskii

In this post, we will see the book Mechanics of Gyroscopic Systems by A. Yu. Ishlinskii.

About the book

This book discusses a fairly wide range of problems in mechanics connected with the practical application of gyroscopes.

The classical studies of A.N. Krylov and B. V. Bulgakov on the theory of gyroscopes are insufficient for solving the problems encountered in the development of new gyroscopic systems. Stricter standards of accuracy have made it necessary to take into account factors formerly neglected and to explain previously undetected experimental facts. New problems in kinematics, the applied theory of elasticity, the theory of oscillations and sta­bility, and the theory of gyroscopes proper have thus arisen

Several new papers on the theory of gyroscopic systems have been published by the author since this book was written (the present monograph is a second slightly revised edition of the book which was first printed in 1952 in a limited issue). Three of them are given here as appendixes.
