In this post, we will see the book Theoretical Mechanics by M. Movnin; A. Izrayelit.
About the book
The new international system of units (SI) is used throughout the text. However, taking into account that the engineers’ system (mkgfs) still finds wide use, the units of this system are also given. Moreover, wherever necessary the relations are indicated between the units of the international and engineers’ systems. Normative and design data are given in both systems of units.
In the presentation of the material primary emphasis is placed on the practical significance of conclusions.
To gain a better understanding of theoretical propositions, the solutions of sample problems are given. All solutions are first carried out in algebraic form and then numerical data are substituted.
Although the book is mainly intended for full-time vocational schools, the large number of detailed and specially selected examples makes it handy for their evening and correspondence departments as well.
The book was translated from Russian by M. Konyaeva was published in 1970 by Mir Publishers.
