* BACKGROUND FOR THE DEVELOPMENT OF GENETIC MECHANICS Mechanics is an ancient science and the first step to facilitate the physical labor of man - has always been associated with the design based on geometric constructions. Creating new or recreating a kind known, the man has always turned to geometric constructions (geometry, plane geometry and solid geometry). These simple ideas from ancient times used by the man in the intellectual, practical, industrial and other activities in the form of genetic information, recorded in various forms (signs, pictures, books, figurines, numbers, etc.) transferred from one generation to the evolutionary their development and synthesis of new TS. Stone Age people tools represent simple forms of bodies, on which all subsequent inventions have appeared in mechanics. The basis of the mechanical gene as a material carrier of hereditary information, created by nature, was put an material point and elementary solid body as a cylinder, parallelepiped, sphere, etc.

Console T-shaped rod of length L with a spindle bearing system a at the overhang and console coordinate table at an altitude of b Scheme is asymmetrical. Asymmetrical arrangement causes the bending strain and distortions (angles 1, 2, 3)
