Упражнение 27 (II). Переведите текст, выделите в тексте случаи употребления пассивной формы и дайте возможные варианты перевода:

COAL

It has been proved that all coals had their origin in the vegetable matter of prehistoric forests. The woody fiber and other vegetable matter were transformed into peat by fermentation due to bacteria. During this process, a great part of the oxygen and hydrogen was eliminated, while the amount of carbon remained practically the same. Subsequently the peaty matter was changed into coal by a process of destructive distillation, which had been caused by great pressure and high temperature. The differences in types of coal can be easily explained by different conditions during this process of evolution. Among these variable conditions by which the formation of coal had been affected the following may be mentioned: time, depth of the bed below the surface of the earth, and amount of disturbance of the bed due to movements of the earth.

Foreign matter was introduced during this movement of the earth. Coal is composed of the following principal elements: carbon, oxygen, hydrogen, nitrogen, and sulphur. However, these are not present solely in their elementary state, but also in various combinations, principally moisture and volatile matter. Consequently, coal is classified into various types according to its constituents; some of these types will be mentioned below.

Peat is an intermediate condition between wood and coal. It is often used as fuel in the Temperate Zone, where it is found in large quantities in the swampy regions. It is commonly cut into blocks and dried in the air.

Bituminous coal is the name which is usually given to coal containing more than 20 per cent volatile matter. Bituminous coal is not susceptible to spontaneous combustion, although care must be exercised in its storage. Since there is a wide range of variation in the characteristics of the bituminous coals, they have been divided commercially into the following classes: coking, cannel, and non-coking. Coking coal, upon being burned gives off considerable gas and tends to fuse together in a pasty mass (coke). Cannel coal has a high percentage of volatile hydrocarbons, ignites easily and is so valuable as a gas-producing coal that it is rarely burned to produce steam.

Non-coking coal does not coke upon being burned and is very extensively used as a fuel to produce steam.

 

THE RUSTING OF METALS

It has long been known that metals can pass from a metallic to an earthy form. One must be careful not to expose unprotected iron to the open air, as under the influence of atmospheric conditions the outer layer of the iron quickly changes into a reddish crust called the rust. One can easily find that this new material is a different substance from iron. The rust is very brittle, it is much lighter, bulk for bulk, than iron and it is not attracted by a magnet.

It was early observed that, although the specific gravity of the earthy product was less than that of the metal, yet there was a much greater bulk of it, and that, in fact, the earthy material weighed more than the original specimen of the metal.

It was Lomonosov who first proved that the extra material came from the air. He placed some tin in a flask and sealed up the mouth of the vessel. The tin was heated and converted into the white powder. Upon weighing the apparatus it was found that no change in weight occurred. It turned out, however, that when the mouth of flask was opened, a good deal of air rushed in and the total weight was then greater. A portion of the original air had joined itself with the tin to form the powder.

Eighteen years later the same experiment was made and the same conclusion drawn from it by Lavoisier. He named the gas taken from the air, oxygen.

It is possible to confirm these conclusions in various ways.

For example, when the air is pumped out of the flask before it is sealed, the metal can be heated in the vacuum indefinitely without rusting. Thus it can be seen that fundamentally rusting is the process in which metals oxidize and form compounds.

It has been estimated that more than 25 per cent of the annual production of iron in the USA is consumed in replacing other iron that has been rendered unserviceable by rusting.

It is necessary, therefore, to wage a constant battle against this chemical process and our immediate concern is how to take care of metallic devices and structures once they enter our possession.

We try to prevent or reduce rusting by various means, such as electroplating, painting or otherwise treating the metals that are susceptible to attack by the agencies of this harmful action.

Упражнение 32 (II). Переведите текст, обращая внимание на модальность:

EQUILIBRIUM

With what can we associate the word “equilibrium”? We ought to know that the term applies equally well to a motor-car moving along a straight road at a constant speed. From a scientific point of view an object can be in equilibrium not only when it is standing motionless, but also when it is moving in a straight line at constant speed. On the other hand it would not be in equilibrium if it were increasing speed or slowing down or provided it were going around a corner.

Evidently, when there are no forces pulling or pushing a body, that body must always be in equilibrium. However, objects with forces acting on them may also be in equilibrium. But, then, the forces must balance; that is, their vector sum is to equal zero. Thus, in the case of the speeding automobile there are forces acting, but they balance each other in pairs. The pull of gravity downward is counteracted by the push of the road upward. The driving force supplied by the motor is balanced by air resistance and other frictional forces. However, as the driving force supplied by the motor is greater than the frictional resistance, the car is accelerated.

But sometimes an object may not be in equilibrium even though the vector sum of all the forces is zero. It may have a tendency to rotate unless all the forces are applied at a single point, or unless the tendency to rotate in one direction balances the tendency to rotate in the opposite.

Thus the second condition for equilibrium is that the tendency to rotate should be zero. There are always two requirements for equilibrium: first, the vector sum of all the forces acting on a body should be zero; and, second, there must be no tendency to rotate, that is, the tendency to rotate the body in one direction must be balanced by the tendency to rotate it in the opposite direction.

We have to point out the importance of equilibrium in any engineering design and construction. For example, if a house is to stand, each of its parts must evidently be in equilibrium.

Rethinking work

Across the planet, the shrinking of opportunities to work for decent pay is a crisis yet to be faced. In the end, the job crisis raises the most fundamental question of human existence: what are we doing here? There is a colossal amount of work waiting to be done by human beings – building decent places to live, exploring the universe, making cities less dangerous, teaching one another, raising our children, visiting, comforting, healing, feeding one another, dancing, making music, telling stories, inventing things, and governing ourselves. But much of the essential activity people have always undertaken to raise and educate their families, to enjoy themselves, to give pleasure to others, and to advance the general welfare is not packaged as jobs. Until we rethink work and decide what human beings are meant to do in the age of robots and what basic economic claims on society human beings have by virtue of being here, there will never be enough jobs.

– From “The end of jobs”, by Richard J. Barnet, senior fellow at the Institute for Policy Studies, in Harper’s magazine, September 1993.

ELECTRIC CURRENT GENERATION

The term “electric current” is used to mean electricity which flows through a conductor, a direct current being a current which flows in one direction only. There are four principal ways by which a direct current can be generated, viz.

1) chemical action;

2) thermal or heat action, the word thermal, coming from the Greek word “therme” which means “heat”;

3) light action;

4) magnetic action.

To set up a current by chemical action, an alkali or an acid is used to react with a metal. Such an apparatus is called an electric cell, a group of two or more cells connected together forming a battery.

To produce a current by thermal action, heat is applied to two unlike metals soldered together in two places, the apparatus of this kind being called a thermoelectric couple or thermocouple, for short. We get the prefix “thermo” from “thermal”, the origin of the last word having been mentioned above. The word “couple” in this term means that two unlike metals or metals and alloys are joined together so that they can be properly heated in the point of the joint.

The reason the thermocouple generates a current is due to the fact that the heat tears the electrons off of the negative inetal at the junction, just as the chemical action of an electric cell tears the electrons off of the zinc electrode. It is these electrons that form the current flowing through the circuit.

To develop a current by light action, light is made to fall on a special kind of a cell, the apparatus to be used in such a case being called a photoelectric cell.

Finally, in order to generate a current, a wire is made to cut, that is, to pass through a magnetic field, this latter being set up either by a permanent magnet or an electromagnet. Where the wire cuts through the magnetic field of a permanent magnet, the apparatus is called a magneto-electric machine or just “magneto”, for short. The wire cutting through the magnetic field of an electromagnet, the apparatus is called a dynamo electric machine, or “dynamo”, for short.

In general there are a number of ways by which electric currents can be generated by magnetic action, all of them being based on the same principle, that of cutting the magnetic lines of force with a conductor.

ELASTICITY

Pulling a rubber band increases its length. However, if you cease pulling it and release one of its ends, the rubber band will quickly return to its original shape and size.

Solids in greatly differing degrees resist being changed in shape, i.e. resist deformation. Some of them, like a rubber band or a steel spring, are called elastic because they return to their original size and shape after having been stretched or compressed. Others are known as elastic because they straighten after having been bent.

Gases and liquids are perfectly elastic. In spite of them having been compressed they return to their original volume after the removing of the applied force.

Air, for instance, is perfectly elastic. If it is compressed and then allowed to return to its original pressure and temperature, it returns exactly to its original volume.

We may define an elastic body as one tending to return to its original shape and size when the deforming force is removed. On the contrary, bodies that are not very elastic do not show the tendency of returning to their original form. Thus, elasticity is the tendency to return to the original condition after deformation.

Careful experiments made on various elastic materials show that there is a simple relationship existing between the acting force and the resistance force. This relationship must have a limit somewhere and the stretching cannot be increased indefinitely.

Elastic limit is the point beyond which one should not attempt deforming the body if it is to return to its original condition.

As we are stretching an elastic object such as a steel spring, for instance, there must come a time when the elastic limit is reached, and then the above-mentioned relationship will not hold any longer. However, stretching the steel spring repeatedly or leaving it stretched moderately has no practical effect upon it. Considering further the example of the rubber band, one finds that the more the rubber band is pulled, the longer it will become until the elastic limit is reached, at last. It is known, however, that rubber can stretch a relatively long distance before reaching the elastic limit.

BORAX

This salt, when crystallized from solution, combines with water forming a hydrate. It is made by adding calcium borate to sodium carbonate solution. It is a white crystalline salt. It is added to the glass, used for enameling and glazing, to make it more fusible and easier to spread in a thin layer. Since it contains but a small proportion of the metallic oxide, it combines with other metallic oxides if fused with them. For this reason, the powdered salt is sometimes sprinkled on tarnished metallic surfaces being soldered or brazed. The heat of the blowpipe melts the borax and the latter removes the oxide and permits perfect running of the solder over the surface.

The borates thus formed are often colored and the colors afford a means of recognizing the metallic compound which produced them.

In chemical analyses a bead of borax, produced by fusion on a platinum wire, is heated with a particle of the unknown compound and its color then examined.

GRAVITY

 

The force of gravity is known to play an important part in many common phenomena of mechanics, as well as in everyday life.

We know the weight of a body to be nothing but the pull of gravity toward the earth. A body is said to weigh one kilogram if the mass of the earth exerts upon it a pull equal to one kilogram.

According to the universal Law of Gravitation, any two objects in the Universe are attracted to each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The Law of Gravitation is universal, of course, but it is impossible to notice the force between two ordinary objects as the attraction between them is too small to be perceptible at all.

But with a body as large as the Earth or the Moon it becomes a different thing. It is this force that holds the planets in their circular orbits and due to this very force the first man-made earth satellite created by Soviet scientists began to circle around our Globe.

We know gravity to pull on every particle of a body so that its weight is actually distributed throughout the body. But a solid body seems to have one point at which it can be supported by a single upward force, this point is called the centre of gravity. In technique the centre of gravity is considered to be the location of the resultant of all gravitational pulls exerted on the body.

Now we are to consider the question of stability, interrelated with gravity.

A book lying on a table is expected to keep its position without any difficulty, as one knows it to be in a state of equilibrium. However, to make it stand on end is not so easy at all. In the same way, a pencil will lie on the table without any tendency to tip over. With some difficulty one can even make it stand on its unsharpened end, but it will not stand at all upon its sharp end.

All common objects differ in their tendency to keep a given position, their stability depending on their shape, weight, and position, and everyday experience shows us that heavy objects are harder to tip over than light ones. The stability of an object is measured by the amount of work to be required to make it take a new position. The lower the centre of gravity, the greater the stability of an object; that is why, to increase the stability of a motor-car, its designer tries to keep the centre of gravity as low as possible.

GENERATION OF STEAM

 

Steam is generated in a boiler by the application of heal to some part which is in close contact with the water it contains. The heat raises the temperature of the water to boiling point and eventually produces steam.

Sensible heat is the one added to the water during the period in which the temperature is rising and while no steam is being generated.

When boiling point is reached, the heat necessary to convert the water into steam is latent one and cannot be measured by the thermometer. Steam heated to a temperature above that which is necessary to make water boil at the given pressure is termed superheated steam.

The total heat of superheated steam is the one required to superheat to the desired temperature, plus to total heat of dry saturated steam above 32 Fahr., and at the superheated pressure.

When steam is generated in a closed vessel, the water and steam cannot be under the influence of the atmosphere, and therefore the pressure shown by the boiler is the pressure which differs from the absolute pressure by an amount equal to atmospheric pressure.

For practical purposes atmospheric pressure is taken as 15 lbs. per sq. in., and therefore the readings for the absolute pressure of steam in a boiler are 15 lbs. greater than those shown by the pressure gauge.
