In this post, we will see the book Engineering Methods for Analysing Strength and Rigidity by G. Glushkov.

**About the book**

The book is a theoretical treatise on the subject of higher order moments. The theory of moments developed into a specific branch of mathematics which became a useful tool for solving complicated problems in structural mechanics. A number of Soviet scientists developed the so-called moment-operational method, which has proved to be extremely efficient for solving various problems of modern engineering. These problems arise when non-linear elasticity must be taken into account, when precise designing of non-uniform structural elements is required, when the loading of a structure is essentially non-uniform, etc.

The moment-operational method has been widely employed for compiling manuals containing numerous tables and formulas for designing beams, arches and frames. A number of scientific research works and textbooks present the theory of moments of higher order methods examples of problems solved by the moment-operational method.

The knowledge of the theory of higher moments as well as of the moment-operational method will serve to extend the field of their application to new problems.

The book was translated from the Russian by *N. Lebedinsky* and was published by Mir in 1974.

Many thanks to *Akbar Azimi* for providing the raw scans. We did the cleaning from 2-in-1 scans. There might be warping in some pages but the text overall is very readable.
