Exercise 5. Read the text and tell what inventions were made in different fields of Engineering. History of Engineering Engineering has existed since ancient times when humans made inventions such as the pulley, lever, and wheel. Each of these inventions is important for the modern engineering, using basic mechanical principles to develop useful tools and objects. The term engineering dates back to 1325, when an engineer (one who operates an engine) originally referred to “a constructor of military engines.” The word “engine” is of even older Latin origin, ingenium, meaning “invention.” Later, as the design of civilian structures such as bridges and buildings developed, the term civil engineering distinguished between the construction of such non-military projects and the older discipline of military engineering. The first electrical engineer is William Gilbert, who was the author of the term "electricity". Mechanical engineer Thomas Savery built the first steam engine in 1698. The development of this device gave rise to the industrial revolution and allowed the beginnings of mass production. Electrical Engineering began with the experiments of Alessandro Volta in the 1800s, the experiments of Michael Faraday, George Ohm and others and the invention of the electric motor in 1872. The work of James Maxwell and Heinrich Hertz in the late 19th century gave rise to the field of Electronics. The later inventions of the vacuum tube and the transistor further accelerated the development of Electronics. The inventions of Thomas Savery and the Scottish engineer James Watt gave rise to modern Mechanical Engineering. The development of specialized machines and their maintenance tools during the industrial revolution led to the rapid growth of Mechanical Engineering in Britain and abroad. Chemical Engineering, like Mechanical Engineering, developed in the nineteenth century during the Industrial Revolution. The role of the chemical engineer was the design of chemical plants and processes. In 1990, with the rise of computer technology, computer engineer Alan Emtage built the first search engine.

Exercise 6. Read the text and underline all types of forces acting on materials. Material Science
Materials Science and Technology is the study of materials and how they can be fabricated to meet the needs of modern technology. Using the laboratory techniques and knowledge of physics, chemistry, and metallurgy, scientists are finding new ways of using metals, plastics and other materials. Engineers must know how materials respond to external forces, such as tension, compression, torsion, bending, and shear. All materials respond to these forces by elastic deformation returning their original size and form when the external force disappears. The materials may also have permanent deformation or they may fracture. The results of external forces are creep and fatigue. Compression is a pressure causing a decrease in volume. When a material is subjected to a bending, shearing, or torsion (twisting) force, both tensile and compressive forces are simultaneously at work. When a metal bar is bent, one side of it is stretched and subjected to a tensional force, and the other side is compressed. Tension is a pulling force; for example, the force in a cable holding a weight. Under tension, a material usually stretches, returning to its original length if the force does not exceed the material's elastic limit. Under larger tensions, the material does not return completely to its original condition, and under greater forces the material ruptures. Fatigue is the growth of cracks under stress. It occurs when a mechanical part is subjected to a repeated or cyclic stress, such as vibration. Even when the maximum stress never exceeds the elastic limit, failure of the material can occur even after a short time. No deformation is seen during fatigue, but small cracks develop and propagate through the material until the remaining cross-sectional area cannot support the maximum stress of the cyclic force. Knowledge of tensile stress, elastic limits, and the resistance of materials to creep and fatigue are of basic importance in engineering. Creep is a slow, permanent deformation that results from steady force acting on a material. Materials at high temperatures usually suffer from this deformation. Loosening of bolts and the deformation of components of machines and engines are all the examples of creep. In many cases the slow deformation stops because deformation eliminates the force causing the creep. Creep extended over a long time finally leads to the rupture of the material.

Meet, suffer, return,propagate,eliminate, support, respond, fabricate, decrease, loosen, exceed … original size, … the needs, … bolts, … volume, … cracks, … the material's elastic limit, … to external forces, … the maximum stress, … from deformation, … material, … the force Exercise 8.

The material to be shaped is called the workpiece. Nowadays most machine tools are electrically driven. Machine tools with electrical drive are faster and more accurate than hand tools. They form the basis of modern industry and are used either directly or indirectly in the manufacture of machines and tool parts. Machine tools may be classified under three main categories: conventional machine tools, presses, and unconventional machine tools. 2……………………………. Among the basic machine tools are the lathe, the shaper, the planer, and the milling machine. Auxiliary to these are drilling and boring machines, grinders, saws, and various metal-forming machines. 3.…………………………….They employ a number of different shaping processes, including shearing, pressing, or drawing. Presses are equipped with dies and punches. Presses are capable of rapid production because the operation time is that needed for only one stroke of the ram. 4……………………………..They employ light, electrical, chemical, and sonic energy; superheated gases; and high-energy particle beams to shape the exotic materials and alloys that have been developed to meet the needs of modern technology. Unconventional machine tools include plasma-arc, laser-beam, electro discharge, electrochemical, ultrasonic, and electron-beam machines. These machine tools were developed primarily to shape the ultrahard alloys used in heavy industry and in aerospace applications and to shape and etch the ultrathin materials used in such electronic devices as microprocessors. Numerical control of machine tools and flexible manufacturing systems have made it possible for complete systems of machine tools to be used for the manufacture of a range of products.

Exercise 5. Read the text and tell what inventions were made in different fields of Engineering. History of Engineering Engineering has existed since ancient times when humans made inventions such as the pulley, lever, and wheel. Each of these inventions is important for the modern engineering, using basic mechanical principles to develop useful tools and objects. The term engineering dates back to 1325, when an engineer (one who operates an engine) originally referred to “a constructor of military engines.” The word “engine” is of even older Latin origin, ingenium, meaning “invention.” Later, as the desig   Система охраняемых территорий в США Изучение особо охраняемых природных территорий(ООПТ) США представляет особый интерес по многим причинам...
