Already in the ancient historical period of the development of mankind - the Stone Age - primitive man used the simplest tools made of stone, wood and bone. When he learned to make tools from iron, the ability to create grandiose wooden technical structures came: mills, military vehicles, huge ships, etc. Rapidly, the technique began to develop with the invention of engines - first on steam traction, then on combustible fuel and electricity. The Great Encyclopedia of Young Technology tells about such machines, mechanisms and devices. This series of books is for schoolchildren who want to know everything and be able to become the smartest and most educated, to understand all spheres of life.
