When solving a problem, first of all establish the physical
laws which it is based on. Then use the formulas expressing
these laws to solve the problem in symbols, and finally
substitute the numerical data in one system of units.

This collection of problems is based on the International System

of Units preferred today in all the fields of’ science, engineering

and economy. Other units can be converted to 51 units with the aid of the relevant tables given in this book.

Each section is preceded by a brief introduction describing the

fundamental laws and formulas which are used to solve the problems. The

solutions to the problems and the reference data are appended at the

end of the book.

The book was translated from the

Russian by A. Troitsky and was edited by G. Leib. The book was first

printed by Mir Publishers in 1971, and fourth reprint appeared in 1987.
