External load

-

External load, external force - acts from the outside (from the side of the environment) to a separate physical system (bodies, structures), constituting a coherent whole with a specific interior. The interior of, for example, the construction system is the entire space which occupies the material of its individual components. In construction, typical external loads are, for example, construction loads, wind, liquid and ground pressure, snow load, etc. External loads can consist of forces and moments concentrated or from different types of distributed loads. In contrast to the own weight of the structure, external loads only act on their surfaces. External loads also include thermal interactions that affect the entire interior of the structure.

The earliest mention of these creatures is dated to the fifth century BC, and its author is Herodotus. According to her, these ants inhabited the deserts of Persia and India and extracted gold from their sands. Several such creatures were kept in the residence of the King of Persia. Gold was to be obtained by caravans made up of several camels in the heat of the day, when the ants were protected underground. You had to do it quickly, because the ants sensed the smell of people and went on the pursuit, and they were deadly dangerous. This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler.
