BASIC HYPOTHESIS . INTRODUCTION Nowadays the building of structures, machines and other engineering structures is impossible without projects previously drawn. The project consists of the drawings and explanation notes presenting the dimensions of the construction elements, the materials necessary for their building and the technology for their building. The dimensions of the elements and details depend on the characteristics of the used materials and the external forces acting upon the structures and they have to be determined carefully during the design procedure. The structure must be reliable as well as economical during the exploitation process. The reliability is guaranteed when the definite strength, stiffness, stability and durability are taken in mind in the structure. The economy of the construction depends on the material’s expenditure, on the new technology introduction and on the cheaper materials application. It is obvious that the reliability and the economy are opposite requirements. Because of that, the Strength of Materials relies on the experience as well as the .
