Weight (mass)

“ Weight has been defined as the measure of the earth's attraction. A body weighing one pound attracts the earth and is attracted by it with a force of one pound, but the same body at the sun's surface would attract the mass of the sun with a force of twenty-seven pounds, since its weight has been increased twenty-seven times by the sun's attraction. ”

“ It is not correct to define mass by the introduction of the idea of weight, because the mass of a body is something independent of the existence of the earth, whereas weight is produced by the attraction of the earth. It is true that weight is a convenient means of measuring mass, but this is only a consequence of the property of gravity which the experiment proves, namely, that the attraction of gravity for a body is proportional to its mass. ”

“ The standard pound is not a “weight,” but a “mass,” and is kept at the Standard's office in London. The pound described above is the avoirdupois pound; the troy pound used only rarely by dealers in precious stones and metals has 5760. grains. The old English pound, which is said to have been the standard of weight from William the Conqueror to Henry VII, was derived from the weight of 7,680 grains of wheat all taken from the middle of the ear and well-dried. ”

“ The first type is always used for accurate purposes. Units of surface are always directly related to standards of length, without any separate standards. Volume is either determined by the lineal dimensions of a space or a solid, or, for accurate purposes, by the mass of water contained in a volume at a given temperature, which again is measured either by liquid measure, or, more accurately, by weight. ”

“ Then weighing what they had borne, whether we should find it to be ten or thirty pounds—I cannot guess how much it might be at this distance—one might safely say, without fear of mistake, "The strength of this young lady is equal to ten, twenty, or thirty pounds"—in other words, "she represents a weight of ten, twenty, or thirty pounds" and by a similar plan people have ascertained the strength of the air—that is, the weight which it represents. They have weighed what it is capable of carrying. ”

“ The weight of objects is not the same all over the world; a thing which weighs thirty pounds in New York would weigh an ounce more than thirty pounds in a spring-balance in Greenland, and nearly an ounce less at the equator. ”

“ Relation of Weight, Size, and Shape to Daily Energy Requirement.—In general the quantity of food required increases with the size of an individual but not at the same rate as the body weight increases. Two persons may be equal in weight, yet very different in height and shape. A tall, slender person requires more food than a short, fleshy person of the same weight. For this reason, size and shape rather than weight are found more accurate in computing the daily food requirement. However, for practical purposes, energy requirement is generally based upon body weight. ”

“ When there is no weight on the spring, the place to which the indicator points is marked zero. When these scales are manufactured, a pound weight is placed so that it pulls on the spring and the indicator is pulled down to another place, and this is marked one. Scales are thus marked for the number of pounds they are to weigh. The spaces between the pounds marked are divided into equal divisions, such as sixteenths which indicates ounces. These scales cannot be relied on for accuracy, for springs stretch or become weaker as they are used. ”

“ In England as well as elsewhere in Europe two pound-units have prevailed from mediæval times, a light pound for weighing articles of high value and a heavy pound for weighing articles of low value. Many of the lighter pounds used in the Latin States are variations of the old Roman standards, others are of Saxon origin, and still others of more recent date. The Italian pounds have varied from 300 to 350 grams, the average being about the weight of the old Roman pound of 325.8 grams. ”

“ If you weighed one hundred and fifty pounds normally, you would suddenly find yourself weighing six hundred pounds more, at seven hundred and fifty pounds altogether. The weight would be so well distributed that you could stand it if you kept your legs firmly braced, but it would be more than a frail chair could endure. ”

“ It is not an uncommon thing for college crews to reduce their weights, by a month’s training, twelve pounds per man. A prize fighter will often come down thirty or forty pounds in [143] preparing for a contest. An instance is cited of a student, who, after carefully weighing himself, sat down to a fifty-five pound rowing-weight, pulled forty-five full strokes a minute for twenty minutes, then, with the same clothing as before, weighed himself, and found he had lost one pound. ”

“ The kilogramme is now, like our pound, a certain metal standard, and the litre is a measure containing, more or less exactly, a kilogramme of water. A perfect litre standard contains 1000 grammes of water at 39·2°; but 1·1 gramme less at 62°, 2 grammes less at 70°, and 3·3 grammes less at 80°, a very frequent summer temperature. For exact correspondence of measure with weight, corrections are always required whether on the imperial or on the metric system. ”

“ The common weight of these halfpence is between four and five to an ounce, suppose five; then three shillings and four pence will weigh a pound, and consequently twenty shillings will weigh six pounds butter weight. Now there are many hundred farmers, who pay two hundred pounds a year rent; therefore, when one of these farmers comes with his half year's rent, which is one hundred pounds, it will be at least six hundred pounds weight, which is three horses load. ”

“ The responsibility of his job weighs on him a good deal. Ответственность за работу его очень тяготит.
to weigh out отвесить. She asked the storekeeper to weigh out five kilograms of sugar. Она попросила продавца отвесить ей пять кило сахару.
weight вес. The weight of the trunk is a hundred kilograms. Вес этого сундуки — сто кило. or Этот сундук весит сто кило. — I've lost a lot of weight since I've been here. С тех пор как я здесь, я много потерял в весе. • гиря. Another two-kilogram weight should make the scale balance. Для равновесия нужна ещё одна гиря в два кило. ”

“ We assume that the wetness weighed half an ounce."
"I don't like skinny females."
"We have another one, less brilliant, but who meets all physical requirements other than weighing a hundred and twenty-three pounds and four ounces."
"Too fat. Can't stand fat women."
"Would you permit Lucy Hollowell to gain half an ounce consciously? She can do it in a few hours. Has a brilliant mind. Can regulate her own glandular flow."
"No. I don't want to marry a woman who is always thinking about her weight, and if she starts now—"
"You're very exacting, Mr. Cornith!" ”

“ In the Tower there is a standard pound. An English silver penny should weigh 1/240 of this pound and 1/20 of its ounce, and the penny-weight may be divided into 32 aces or little grains. But there is another old-established pound used for all goods but gold and silver, bread and drugs. Our regard for the unity of weight forbids us to describe this pound otherwise than by mentioning that a wine-gallon contains 8 of these pounds weight of wine or of water, that 8 larger gallons each containing 8 pounds, not of wine, but of wheat, make a Bushel ”

“ Nevertheless that which excels in size shows greater powers, since it seizes greater weights and has a wider orbe of virtue. For a loadstone weighing one ounce does not lift a large nail as does one weighing a pound, nor does it rule so widely, nor extend its forces; and if from a loadstone of a pound weight a portion is taken away, something of its power will be seen to go also ”

“ The normal weight of a man five feet in height is 120 pounds; of a man five feet ten inches, 169 pounds. Now, suppose the latter really weighs 300 pounds by accumulation of fat, what results but that all this superfluous matter has to be supplied with capillaries, and these have to get blood from vessels only constructed to circulate the original quantity? No wonder is it that the circulation is enfeebled and impeded! By this increase of adipose there is no increase of propelling force. ”

“ In the gradation of real weights, measures, and coins, it is important to adopt those grades which are most convenient, which require the least expense of capital, time, and labor, and which are least likely to be mistaken for each other. What, then, is the most convenient gradation? The base two gives a series of seven weights that may be used: 1, 2, 4, 8, 16, 32, 64 lbs. By these any weight from one to one hundred and twenty-seven pounds may be weighed. ”

“ It is the custom in many factories to balance the scales so that a pound or so is taken out of each mess, in order to help make "a big average" for the season. That is, every mess is made to weigh a pound or so less than its actual weight, and is so entered on the book. ”

“ In the second class of cases the fraction of the unit quantity is a quantity of the same kind, but cannot be determined with absolute exactness. Weights come in this class. The ounce, for instance, is one-sixteenth of the pound, but it is impossible to find 16 objects such that their weights shall be exactly equal and that the sum of their weights shall be exactly equal to the weight of the standard pound. ”

“ Perhaps you will wonder how it is that if we have a weight of 15 lbs. pressing on every square inch of our bodies, it does not crush us. And, indeed, it amounts on the whole to a weight of about 15 tons upon the body of a grown man. It would crush us if it were not that there are gases and fluids inside our bodies which press outwards and balance the weight so that we do not feel it at all.
This is why Mr. Glaisher's veins swelled and he grew giddy in thin air. ”

“ That load is made up of two parts, the “constant” weights of cooking-outfit, rifle, instruments, etc., and the “variables” comprising supplies which are constantly decreasing as consumed by men and dogs. For every pound of “constant” weight that can be saved by elimination or refinement a pound of pemmican can be substituted, and this is a day’s, or, in an emergency, two days’, ration for a man or a dog. A saving of nine pounds in the “constants” represents a full day’s rations for a driver and his eight dogs, and this transformed into distance may mean anywhere from ten to forty miles. ”

“ All units must be assumed to be equal in that other respect; and this is never accurately true, for one actual pound weight is not exactly equal to another, nor one measured mile's length to another; a nicer balance, or more accurate measuring instruments, would always detect some difference. ”

“ One pound at A will, according to the rule, balance 2 at B, and 2 at B will balance 4 at C, and 4 at C will balance 8 at D. Therefore 1 pound at A will balance 8 pounds at D. And you see that an equilibrium is effected when the power is to the weight as the product of all the short arms is to the product of all the long arms. The compound lever is used in weighing heavy loads—as hay, coal, etc. You have a representation of the arrangement in Fig. ”

“ There are also measures of weight, ounces, pounds and tons. Now these different measures are the same all over the United States. A pound of butter in New York is the same as a pound of butter in California. There are other countries that do not have measures like ours. France, for example, has the metric system. Should you go into a dry goods store in Paris you would not ask for a yard of cloth, but for a meter.
God's measures are the same. God has a measure for girls and boys, and that measure is the same in Ohio, Mexico, England or Spain. ”

“ It is only because a yard-stick has a fixed and definite length of its own that we are enabled to measure the length of other things by it. It is only because a pound weight has a fixed and definite weight of its own that we are enabled to measure weight of other things by it. ”

“ I dare say you are aware that the air we breathe possesses weight. If you weigh a bottle under ordinary circumstances, containing air, and nothing else, and afterwards pump the air from it and weigh it again, you will find that its weight is reduced; it weighs less than when filled with air. Now if I weigh two bodies of different sizes, but of equal weights, in the open air, and then dip balance and all into water, I shall find that they are no longer equiponderant. Each article in weighing loses as much weight as is equivalent to its own bulk of the medium in which it is weighed. ”

“ You must understand that the usual mode of doing business in coal-sheds is this: all the weights only weigh one half of what they are represented to weigh. For instance, the one which is used as the fifty pound weight is hollow, and is, therefore, made as large in outward appearance as the real fifty pound weight; whereas, in consequence of being hollow, it actually only weighs twenty-five pounds. ”

“ What it comes to is this, that if you have a ten-pound weight and a one-pound weight and you drop them together, the ten-pound weight will fall ten times as quickly. The magnitude of the weight settles how quickly it shall fall. That seems to us so astonishing that we can hardly imagine that any one believed it. ”

“ The great pound is just two small pounds; they call the great weight by the name of beasemar, and the small they call the skallawaight. With this small weight they weigh their silver coins, of which the Emperor hath commanded to put to every small pound three rubbles of silver; and with the same weight they weigh all grocery wares, and almost all other wares, which come into the land, except those which they weigh by the pode, as hops, salt, iron, lead, tin, and batrie, with divers others. Notwithstanding, they used to weigh batrie more often by the small weight than by the great. ”
