Pattern-making relates to the construction of duplicate models for the moulded parts of machinery, and involves a knowledge of shrinkage and cooling strains, the manner of moulding and proper position of pieces, when cast, to ensure soundness in particular parts. As a branch of machine manufacture, pattern-making requires a large amount of special knowledge, and a high degree of skill; for in no other department is there so much that must be left to the discretion and judgment of workmen.このページの先頭です
ONE:A leading principle in machinery of transmission that more than any other furnishes data for strength and proper proportions is, that the stress upon the machinery, whatever it may be, is inverse as the speed at which it moves. For example, a belt two inches wide, moving one thousand feet a minute, will theoretically perform the same work that one ten inches wide will do, moving at a speed of two hundred feet a minute; or a shaft making two hundred revolutions a minute will transmit four times as much power as a shaft making but fifty revolutions in the same time, the torsional strain being the same in both cases."Get me food," he said; "they starve you in those places yonder. I have tobacco, but my stomach craves for food. Go and get me food. I'll go and lock the area door so that you may not give way to a desire to take the air. After that you can find me something."

ONE:Xenophon gives the same interest a more edifying direction when he enlivens the dry details of his Cyropaedia with touching episodes of conjugal affection, or presents lessons in domestic economy under the form of conversations between a newly-married couple.107 Plato in some respects transcends, in others falls short of his less gifted contemporary. For his doctrine of love as an educating processa true doctrine, all sneers and perversions notwithstandingthough readily applicable to the relation of the sexes, is not applied to it by him; and his project of a common training for men and women, though suggestive of a great advance on the existing system if rightly carried out, was, from his point of view, a retrograde step towards savage or even animal life, an attempt to throw half the burdens incident to a military organisation of society on those who had become absolutely incapable of bearing them.It took only seconds for the race to conclude.

THREE:I think proper to point out these peculiarities, not so much from any importance they may have in themselves, but to suggest critical investigation, and to dissipate any preconceived opinions of forging being a simple matter, easy to learn, and involving only commonplace operations.

TWO:Her reserve told me that I would not get much information here, and, finishing my beer, I asked:Leona inclined her head as if in consent.
TWO:I spent three hours in the small room with my silent companions. At last I was called, and appeared once more before the casual court-martial.

It is not intended to claim that this platen-reversing motion cannot, like any other mechanical movement, be resolved mathematically, but that the mechanical conditions are so obscure and the invention made at a time that warrants the supposition of accidental discovery."There is nothing to explain. Officer, you can take your oath on it?"210"Kill him," urged the Countess. "Kneel down and pin that wrap over his face. He is an old man, and the drug has affected his heart. He will go off quietly in his sleep. Then you can throw him down the well in the courtyard of the Corner House."Physical strength, bone and muscle, must be elements in successful engineering experience; and if these things are not acquired at the same time with a mechanical education, it will be found, when ready to enter upon a course of practice, that an important element, the "propelling power," has been omitted.
