In this post, we will see the book *Strength of Materials* by *R. Kinasoshvili.*

A book covering various aspects of strength of materials. The topics covered are succinct and with basic definitions and requisite mathematics. Each chapter has a set of “Check Questions” in the end.

The development of the foundations for the design of structural members is the subject matter of a science called the strength of materials.

Without knowledge of the fundamentals of strength of materials it is impossible to construct even a simple machine satisfying the technical requirements placed on each construction.

The book was translated from the Russian by *M. Konyaeva* and was published by Mir in 1978 (second print).

Many thanks to *Akbar Azimi* for the raw scans.
