Engineering rock mechanics. Part 2. Illustrative worked examples / Инженерная механика горных пород. Часть 2. Наглядные практические примеры

There are two reasons why it is important to understand and use engineering rock mechanics units correctly: engineering rock mechanics calculations used for rock engineering design should be numerically correct; and to use engineering rock mechanics properly, an understanding of units is necessary.
We have used standard symbols and the SI (International System) of units. There are seven base units in the SI system: length, mass, time, electric current, thermodynamic temperature, amount of substance and luminous intensity. These base units are dimensionally independent.  <...>
