Сопромат. Доцент Цветков рассказывает студентам ПГС МГСУ про первый в их жизни расчет на прочность!!

An example of calculating the strength and stiffness of a rod under axial tension is considered. A brief theory of axial tension (compression) is presented: what it is, what internal force and stress arises, the strength condition, the formula for determining elongation (shortening), and the concept of longitudinal stiffness. The basic principles of strength calculations using the limit state method are discussed: load safety factor, service condition factor, material safety factor, standard and design loads, and standard and design material resistance. The cross-section of a rod made from a steel rod is selected. A stiffness check is performed. A bonus is a Cinderella story.
