On the Mechanics of Live Nature in the Works of V.P. Goryachkin,problem “Human—Machine—Environment” in his works. A specific property of most agricultural machines, including modern ones, is the fact that a human operator is needed to control these machines. Starting from his very early works in agricultural mechanics and theory of agricultural machinery, Goryac

,New Trends in Learning Through 3D Modeling of Historical Mechanism’s Model,el. The peculiarity of the mentioned planetary model is that the rotational movement of input link of the mechanism is converted into the forward movement of its output link. A detailed analysis of so-called “Ferguson’s Paradox” was conducted as well as the biography of James Ferguson was recounted.

19th c. Olivier String Models at Cornell University: Ruled Surfaces in Gear Design,tring models illustrating concepts of descriptive geometry were employed in the 19th and early 20th centuries as teaching and visualization aids for engineering, architecture and mathematics. The carefully crafted “Olivier models” are composed of finished wooden bases, brass armatures and colored th
