"Rotary motion" Quotes from Famous Books
 ... String.—To the extremity of a string about 18 in. in length attach a chain about 15 in. in length, the extremities of which are united. Holding the string vertically between the fingers, give it a rapid rotary motion. The chain will first open out as seen at A of the figure. Upon increasing the velocity of rotation, it will be thrown out farther and farther until it finally forms a circle in a horizontal plane. In this motion, the string forms a sort of conoidal surface, distended ...

... ballast should be so adjusted that there is nearly equilibrium before leaving, else the rapidity of ascent is too great, and has to be checked by parting with gas. It is almost impossible to liberate the balloon in such a way as to avoid giving it a rotary motion about a vertical axis, which continues during the whole time it is in the air. This rotation makes it difficult for those in the car to discover in what direction they are moving; and it is only by looking down along the ...

... inserted the extremity of the tube R, after being twice bent at a right angle. P is also in direct connection with the efflux tube E, E and R serving to convey the dye or bleach solutions to and from the reservoir C. The combination of the rotary motion communicated to A, which contains the goods to be dyed or bleached, with the very thorough penetration and circulation of the liquids effected by means of the vacuum established in B, is found to be eminently favorable to the rapidity and evenness of ...

... sufficient and complete account of man and his dwelling-place. If, says he, it is true that one generation comes and another goes, and the earth abides for ever, and if that is all that has to be said, then all things are full of labour. There is immense activity, and there is no progress; it is all rotary motion round and round and round, and the same objects reappear duly and punctually as the wheel revolves, and life is futile. Yes; so it is unless there is something more to be said, and the life that is thus futile ...

... been a vastly convenient thing for humanity had it chanced that the earth had so accommodated its rotary motion with its speed of transit about the sun as to make its annual flight in precisely 360 days. Twelve lunar months of thirty days each would then have coincided exactly with the solar year, and most of the complexities of the calendar, which have so puzzled historical students, would have ...

... attributed to material atoms from the time of Lucretius downward may be dispensed with. Somewhat in the same way that a loosely suspended chain becomes rigid with rapid rotation, the hardness and elasticity of the vortex-atom are explained as due to the swift rotary motion of a soft and yielding fluid. So that the vortex-atom is really indivisible, not by reason of its hardness or solidity, but by reason of ...

... greater thickness. This cylinder is traversed by a shaft, C, to which it is keyed, and which passes through the center of the aperture drilled. This shaft is connected with the cylinder, A, through the intermedium of cross bars, D, and transmits thereto a rapid rotary motion, which is received at the upper part from a telodynamic wire that passes through the channel of the horizontal pulley, P. This latter is supported by a frame consisting of three uprights, Q Q, strengthened by stays, R R, fixed ...

... solution of ferric chloride to one ounce of hydrochloric acid.[6] Fill a small porcelain dish one-third full of this solution; add an equal volume of milk and heat slowly over a flame nearly to the boiling point, giving the dish a rotary motion to break up the curd. If formaldehyde is present, the mass will show a violet color, varying in depth with the amount present; if it is absent, the ...

... kilu, with which the game was played, was an oval, one-sided dish, made by cutting in two an egg-shaped coconut shell. The object of the player was to throw his kilu so that it should travel with a sliding and at the same time a rotary motion across the matted floor and hit the wooden block which stood before the one of his choice on the side opposite. The men and the women took turns in playing. A successful hit entitled the player to claim a kiss from his opponent, a toll which was exacted at once. Success in winning ten points ...

... them into contact with normal positive-matte—That's done in a chamber the size of a fifty-gallon barrel, made of collapsium and weighing about a hundred tons. Then you have to have a pseudograv field to impart rotary motion to your cosmic-ray beam, and the generator door that would lift ten ships the size of the Lester Dawes. Then you need another fifty to a hundred tons of collapsium to shield your cutting-head. The cutting-head alone weighs three tons. The rotary beam that does the cutting," he mentioned ...

... of the Repository of Models. On rising 6500 English feet, they commenced their observations. The magnetic needle was attracted as usual by iron, but it was impossible for them at this time to determine with accuracy its rate of oscillation, owing to a slow rotary motion with which the balloon was affected. The voltaic pile exhibited all its ordinary effects, giving its peculiar copperas taste, exciting the nervous system, and causing the decomposition of water. At the elevation of 8600 feet, the animals which they carried with them appeared to ...

... the equator, moving with the earth's rotary motion, has a greater velocity than the earth itself at high northern or southern latitudes, and consequently appears to gain an eastward motion in its progress toward the poles. Without friction, this relative eastward motion would increase as the air moves toward the poles, and diminish at ...

... lever. The aviator has merely to depress this pedal with his foot, when the box is opened and the whole of the contents are released. The fall at first is somewhat erratic, but this is an advantage, as it enables the darts to scatter and to cover a wide area. As the rotary motion of the arrows increases during the fall, the direct line of flight becomes more pronounced until at last they assume a vertical direction free from all wobbling, so that when they alight upon the target they are ...
