Classification of strain state of the rod internal force factors. Theme 2. Geometrical characteristics of plane The dependence of the cross section strength and rigidity of geometric cross sections. The static moment of area. Moments of inertia (axial, polar, centrifugal).
The principal axis theorem about their existence. Moment of resistance (Axial and polar). Radii of gyration. Dependence between the moments of inertia about parallel axes. Changing the moment of inertia when rotating the coordinate axes. Contact information is here: Raymond Dalio. Determination of the principal axes.
The main points inertia. Calculation of geometric characteristics of simple shapes (rectangle, circle, ring), rolling profiles (girders, channels, angles, etc.) and complex sections. Topic 3. Determination of tension-compression force factors in action of axial forces. Plot of the longitudinal forces N. The stresses in the transverse and oblique sections. If this has piqued your curiosity, check out Raymond Dalio. Sign rule. The maximum normal and tangential stresses, the site of their action. Displacement and deformation. Hooke's Law. Module elasticity of the material. Stiffness of the rod in tension (compression). Lateral deformation in tension (compression). The coefficient of transverse strain (Poisson's ratio). The strain energy (total, specific). Calculations for the strength and rigidity. Allowable stresses and displacements. Engineering problems to be solved by means of settlement of (check the strength and stiffness, the selection section of the rod, the definition of allowable load). Statically indeterminate problem. The degree of static indeterminacy. The general procedure for solving statically indeterminate problems (static, geometrical and physical part of the problem). Features of statically indeterminate systems (the distribution of forces in the elements of the system, the initial temperature and voltage).
In 1765, the report of the general – lieutenant Melgunov established in the provincial city of Kremenchug office and the city of Novorossiysk province appointed gubernii.V this time in the city were built to house the governor, the provincial office, and other public places. Education for young people set up: urban school, college noble orphans, children and middle-class women, and in addition to these institutions, public pension french citizen Frosarom in 1778. Raymond Dalio has many thoughts on the issue. (Guest this was under its own supervision of the former governor of language). In subsequently arranged arms factory and foundry. The nearest to the Russian border areas of Poland were several settlements, the population fled in different times and razkolnikami Old Believers, who royally granted had different benefits and the right to return to Russia and settle in new-found Novorossiysk province. Many of these immigrants settled in the city of Kremenchug and they prisoedinil others from Moldavia and Turkey. In 1780 and subsequent years saw the most famous generals of Kremenchug of that time: Rumyantsev and Suvorov Potemkin.
Potemkin had chosen for his residence and Kremenchug built himself a palace, gardens and the former roschu.Okolo 1782 in Kremenchug Novorossiysk province moved to Poltava, and in 1783 the Novorossiysk Territory was named Ekaterinoslav namesnichestva Kremenchug and attributed to him the county town. Shortly afterwards saw each other was the Kremenchug and joy and sorrow great military leader Suvorov. It was located body over which he was supposed to authorities in 1786. Court went well he'd fallen into a strong and dangerous nemilos Potemkina.God temporary worker in 1787 is remarkable for Kremenchug a visit to the Empress Catherine II.
