FORE:"You wouldn't force her to confess?"When a piece is placed on an anvil, and struck on the top side with a certain force, the bottom or anvil side of the piece does not receive an equal force. A share of the blow is absorbed by the inertia of the piece struck, and the effect on the bottom side is, theoretically, as the force of the blow, less the cushioning effect and the inertia of the pieces acted upon.
FORE:(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?"How did you find that out?" Leona cried, startled off her balance.
FORE:Evidently he seemed to confide in me, and told me that they had been ordered to clear the north-east corner of Belgium of enemies, and that by and by they were going to march upon Lanaeken first of all.
FORE:No new clues offered themselves. He detached one of the hard, adhering chunks of gum and dropped it into his pocket, just in case, he said, half-grinning, just in case they transfer themselves somewhere else. Ill leave twenty-nine of themand see."We remind the citizens that by order of the general commanding the German troops, those who have arms in their possession must deliver them immediately to the authorities at the Provincial Palace under penalty of being shot.
FORE:"Are you not going to speak first?" Lawrence asked.
FORE:It may be remarked as a general rule that the hardness of cutting tools is "inverse as the hardness of the material to be cut," which seems anomalous, and no doubt is so, if nothing but the cutting properties of edges is considered; but all cutting edges are subjected to transverse strain, and the amount of this strain is generally as the hardness of the material acted upon; hence the degree of temper has of necessity to be such as to guard against breaking the edges. Tools for cutting wood, for example, can be much harder than for cutting iron, or to state it better, tools for cutting wood are harder than those usually employed for cutting iron; for if iron tools were always as carefully formed and as carefully used as those employed in cutting wood, they could be equally hard.Leona Lalage kept her face half hidden behind her fan. For the life of her she could not tell whether this man was playing with her or not Hitherto men had been her puppets, hitherto she had regarded all of them as fools. Lawrence smoked calmly on, as if he were discussing the weather or something equally exciting.
