      The lifting strain at the front end of a platen is of course increased as the height at which the cutting is done above its top, but this has not in practice been found a difficulty of any importance, and has not even required extra length or weight of platens beyond what is demanded to receive pieces to be planed and to resist flexion in fastening heavy work. The reversing movement of planing machine platens already alluded to is one of the most complex problems in machine tool movement.へい妤欷ぐろ(1.) What kind of strains are shafts subjected to?—(2.) What determines the strength of shafts in resisting transverse strain?—(3.) Why are shafts often more convenient than belts for transmitting power?—(4.) What is the difference between the strains to which shafts and belts are subjected?—(5.) What is gained by constructing a line shaft of sections diminishing in size from the first mover?—(6.) What is gained by constructing line shafts of uniform diameter?�抒廿い

      I had to listen to a prolonged hymn of praise of the Netherlanders, who were such sensible people, and the best friends of the Germans; protestations which did not interest me in the least at that moment. On the contrary, it struck me as deplorable that this man did not say a single word of his own accord about the horrible thing happening close by: the destruction of an entire community! He did not seem to attach any importance to it....き撙踏栈�れHaving thus far treated of such general principles and facts connected with practical mechanics as might properly precede, and be of use in, the study of actual manipulation in a workshop, we come next to casting, forging, and finishing, with other details that involve manual as well as mental skill, and to which the term "processes" will apply.沾

      Besides the machine tools named, there are special machines to be found in most works, machines directed to the performance of certain work; by a particular adaptation such machines are rendered more effective, but they are by such adaptation unfitted for general purposes.互ケ�ゥぅぅヒCHAPTER XXXI. PLANING OR RECIPROCATING MACHINES.ア

      Formerly an apprentice entered a shop to learn hand skill, and to acquaint himself with a number of mysterious processes; to learn a series of arbitrary rules which might serve to place him at a disadvantage even with those whose capacity was inferior and who had less education; but now the whole is changed. An engineer apprentice enters the shop with a confidence that he may learn whatever the facilities afford if he will put forth the required efforts; there are no mysteries to be solved; nearly all problems are reached and explained by science, leaving a greater share of the shop-time of a learner to be devoted to studying what is special.ぅΕd━d"A German officer came nearer, and, uncovering his head, said in a voice trembling with emotion: 'General, what you performed is admirable!' Evidently these words slightly comforted the defender of Liège, who before long was removed by motor-car to an ambulance in the town."喂イ俏睿�イ毯ぅヘ簸

      I was greatly astonished to see a little old man sitting by his house, while all those in the neighbour118hood were burning. His own dwelling had escaped without much damage, and was only hit by rifle bullets. He told me that his family had fled, his son with wife and all children but one, a small boy. At length he left also, but had lost his way outside the town, and returned to his house, where the Germans "allowed" him to remain. I considered that I might after all sleep better in that house than yonder among the soldiers, and asked the little man whether he would put me up for the night. He did not object at all; but in spite of my pressing, he refused absolutely to accept any payment.を攥85自圣谖缪Many clerical gentlemen connected with the University had been ill-treated in the most atrocious manner. The architect Lenertz, a native of Luxemburg, also connected with the University, had been shot, for no reason at all, before the eyes of his wife at the moment that he left the house. And Louvain was so effectively cut off from the outer world that in most convents I was asked whether the rumour was true that the Pope was dead! And at that time his successor had already been appointed.─瑗ゥ

      �たずゥイド�サハイ蓼━ぽIn making designs it is best to employ no references except such as are carried in the memory. The more familiar a person is with machinery of any class, the more able he may be to prepare designs, but not by measuring and referring to other people's plans. Dimensions and arrangement from examples are, by such a course, unconsciously carried into a new drawing, even by the most skilled; besides, it is by no means a dignified matter to collect other people's plans, and by a little combination and modification produce new designs. It may be an easy plan to acquire a certain kind of proficiency, but will most certainly hinder an engineer from ever rising to the dignity of an original designer.抠ねゥ

      A standard of lineal measures, however, cannot be taken from one country to another, or even transferred from one shop to another without the risk of variation; and it is therefore necessary that such a standard be based upon something in nature to which reference can be made in cases of doubt.逆やい叽ゥぅThe combination of several functions in one machine, although it may not seem an important matter to be considered here, is nevertheless one that has much to do with the manufacture of machines, and constitutes what may be termed a principle of construction.欷无ぅぅ"I don't know yet.

      �堡饱蔽イイイTo attempt a generalisation of the operations of the fitting shop in this manner may not seem a very practical means of understanding them, yet the application will be better understood as we go farther on.朔激ご"Well, sir, not much beyond what you are sure to know already: that Japan declared war against Germany; that the Russians invaded Germany; that the French gained some important victories in Alsace; that the German fleet lost some ships...."博讠绀钉ふぅ
