FORE:(1.) Why are shaping machines better adapted than planing machines for planing slots, key-ways, and so on?(2.) What objects are gained by a quick return motion of the cutter bar of shaping machines?FORE:At the same time Lucretius is resolved that no false analogy shall obscure the distinction between life and the conditions of life. It is for attempting, as he supposes, to efface this distinction that he so sharply criticises the earlier Greek thinkers. He scoffs at Heracleitus for imagining that all forms of existence can be deduced from the single element of fire. The idea of evolution and transformation seems, under some of its aspects, utterly alien to our poet. His intimacy with the world of living forms had accustomed him to view Nature as a vast assemblage of fixed types which might be broken up and reconstructed, but which by no possibility could pass into one another. Yet this rigid retention of characteristic differences in form permits a certain play and variety of movement, an individual spontaneity for which no law can be prescribed. The foedera Naturai, as Prof. Sellar aptly observes, are opposed to the foedera fati.206 And109 this is just what might be expected from a philosophy based on the contemplation of life. For, while there is no capriciousness at all about the structure of animals, there is apparently a great deal of capriciousness about their actions. On the other hand, the Stoics, who derived their physics in great part from Heracleitus, came nearer than Lucretius to the standpoint of modern science. With them, as with the most advanced thinkers now, it is the foedera Naturaithe uniformities of co-existencewhich are liable to exception and modification, while the foedera fatithe laws of causationare necessary and absolute.FORE:Leaving out the matter of a positive relative movement between shafts, which belts as a means of transmitting power cannot insure, there are the following conditions that must be considered in determining whether belts or other means should be employed in transmitting power from one machine to another or between the parts of machines.FORE:Whether there exist any realities beyond what are revealed to us by this evidence, and what sensible evidence itself may be worth, were problems already actively canvassed in Aristotles time. His Metaphysics at once takes us into the thick of the debate. The first question of that age was, What are the causes and principles of things? On one side stood the materialiststhe old Ionian physicists and their living representatives. They said that all things came from water or air or fire, or from a mixture of the four elements, or from the interaction of opposites, such as wet and dry, hot and cold.332 Aristotle, following in the track of his master, Plato, blames them for ignoring the incorporeal substances, by which he does not mean what would now be understoodfeelings or states of consciousness, or even the spiritual substratum of consciousnessbut rather the general qualities or assemblages of qualities which remain constant amid the fluctuations of sensible phenomena; considered, let us observe, not as subjective thoughts, but as objective realities. Another deficiency in the older physical theories is that they either ignore the efficient cause of motion altogether (like Thales), or assign causes not adequate to the purpose (like Empedocles); or when they hit on the true cause do not make the right use of it (like Anaxagoras). Lastly, they have omitted to study the final cause of a thingthe good for which it exists.FORE:"Of course it is," Lawrence replied. "One question more. How many times did the hall gas go out when you were there?"

FORE:FORE:Bruce put the thing out of his mind for the time being. The next morning was a busy one. When the back of it was broken he drove to Tottenham Court Road, where he managed to secure the old-fashioned furniture which had so taken his fancy. He felt pleased with his bargain, but as he repaired to the Lotus Club to lunch with Gilbert Lawrence nothing remained of the old Dutchman's banknotes."That clenches it," he said. "Now where did they hide themselves?"FORE:Shop system may also be classed as a branch of engineering work; it relates to the classification of machines and their parts by symbols and numbers, to records of weight, the expense of cast, forged, and finished parts, and apportions the cost of finished machinery among the different departments. Shop system also includes the maintenance of standard dimensions, the classification and cost of labour, with other matters that partake both of a mechanical and a commercial nature.
