Text 1 THE SUBJECT OF MECHANICS The progress of technology confronts the engineer with various problems connected with structural design, manufacture and operation of various machines, motors and means of motion, such as automobiles, steam engines, planes, ships and rockets. The solution of such problems is based on certain general physical principles - the laws that govern the motion and equilibrium of material bodies. The branch of physics that deals with the behavior of physical bodies subjected to forces or displacements, and the subsequent effect of the bodies on their environment is called mechanics. Mechanics has its roots in several ancient civilizations. During the early modern period, scientists such as Galileo, Kepler and especially Newton, laid the foundation for what is now known as classical mechanics. Much of the content of this subject was created in the 18-th and 19-th centuries. Classical mechanics is often viewed as a model for other so-called exact sciences. Mechanics constitutes a central part of technology, the application of physical knowledge of the world for defined purposes. In this connection, the discipline is often known as engineering or applied mechanics. In this sense mechanics is used to design and analyze the behavior of structures, mecha- nisms and machines. Finally, as it is known, the study of mechanics gave birth to important fields of mechanical engineering, aerospace engineering, civil engineering, structural engineering, biomedical engineering and biomechanics and other branches of technology. Thus, mechanics, as it is stated above, is the science that deals with the solution of all problems connected with the motion or equilibrium of material bodies and the resulting interactions between them. By motion in mechanics we mean any change in relative positions of material bodies in space that takes place in the course of time. By mechanical interaction between bodies is meant such a reciprocal action which changes the state of motion or the shape of the bodies. The physical measure of such mechanical interaction is called force. According to the above mentioned problems engineers divide mechanics into statics, that deals with bodies at rest, and dynamies, concerning the motion of bodies. Dynamics, in its turn, consists of kinematics and kinetics. Kinematics deals with the geometric aspect of motion without considering the origins of forces. Kinetics studies the motion of bodies under the action of forces.

Answer

Механика изучает поведение материальных тел, которые подвергаются действию сил или перемещениям, а также последующие влияния этих тел на их окружение. Это важная область физики, которая является основой для решения различных инженерных задач, связанных со структурным проектированием, производством и эксплуатацией машин, автомобилей, самолетов, судов и ракет.

Механика имеет глубокие исторические корни и развивалась через учения таких ученых, как Галилей, Кеплер и особенно Ньютон, которые заложили основы классической механики. Эта наука, как правило, рассматривается как модель для других точных наук.

Механика делится на несколько подразделов. Статика изучает тела, находящиеся в состоянии покоя, тогда как динамика касается движения тел. Динамика включает в себя две важные составляющие: кинематику, которая исследует геометрические аспекты движения без учета сил, и кинетику, которая изучает движение тел под воздействием сил.

Таким образом, механика — это наука, которая решает вопросы, связанные с движением и равновесием материальных тел, а также взаимодействиями между ними. Основным физическим понятием, описывающим эти взаимодействия, является сила. Механика является центральной частью технологий и исследуется в таких областях, как механическая, аэрокосмическая, гражданская и биомедицинская инженерия.
