What can you infer about the text accompanying the images?

The text is in Russian and contains elements of scientific notation and terminology. It seems to be providing explanations, calculations, or problem statements related to the diagrams. For example, there are numerical values with units (e.g., 'H' for Newtons, 'kg' for kilograms) and mathematical expressions. The structure suggests it could be a textbook excerpt, a lab manual, or a set of physics problems.
