Action Front Because it has only one knife edge, and does not involve the adjustments of the convertible pendulum, this one is called “invariable.” Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z The cross must be so made that the knife edges will be in the same plane. The Boy Mechanic: Volume 1 700 Things for Boys to Do The knife edge is placed at the middle, then moved a short distance towards the mouthpiece. Composition-Rhetoric The prow of the car follows the lines generally adopted in high speed torpedo boat design; there is a sharp knife edge stem with an enclosed fo'c's'le, the latter housing the gun. Aeroplanes and Dirigibles of War Behind burnt-orange portières of great length and great depth of nap, the Twenty-Four Follies, each tempered like a knife edge, stood identically poised for the first clash of Negroid music from a Negroid orchestra. Humoresque A Laugh on Life with a Tear Behind It The knife edge rested on a steel plate. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z This can be determined by placing two of the knife edges on the jaws of a vise and then laying two rules across the other two edges. The Boy Mechanic: Volume 1 700 Things for Boys to Do A voice with a knife edge to it cut through the room and made them all shiver. Lo, Michael! The results of comparing the pendulums were discordant, and the knife edge of the faulty pendulum had very sensibly altered. Autobiography of Sir George Biddell Airy We gained the top of the cliff, a mere knife edge in places, where we worked our way along, straddling the rock. American Big Game in Its Haunts Thus, the mass of the suspending apparatus could be neglected in the theory of motion of the pendulum about the knife edge. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z It was masked by trees for some distance, and then came out as a bare knife edge of rock and earth. Noto: an Unexplained Corner of Japan The knife edge of the ridge is generally not much over a foot wide. A Voyage to Arcturus And this April night air had a knife edge. The Research Magnificent The convertibility of the pendulum was constituted by the provision of two knife edges turned inwards on opposite sides of the center of gravity. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z To the left is a “vertical comparator” designed by Repsold to measure the distance between the knife edges of the pendulum. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z He constructed a convertible pendulum with two knife edges and with it determined the absolute value of gravity at the house of Henry Browne, F.R.S., in Portland Place, London. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z He then constructed a similar compound pendulum with only one knife edge, and swung it to determine relative values of gravity at a number of stations in the British Isles. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z Bessel found this “cylinder of unrolling” superior to the clamps and knife edges of earlier pendulums. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z It was intended by the mechanicians that equality of times of oscillation about the knife edges would be achieved by adjusting the position of a movable disk. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z They were made of bars, of iron in one case, and of brass in the other, and each had two knife edges at opposite ends equidistant from the center. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z Plantamour found it impracticable to adjust a disk until the times of swing about each knife edge were equal. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z Gen. Baeyer stated that the distance of 1 meter between the knife edges of the Prussian Repsold-Bessel pendulum made it unwieldy and unsuited for transport. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z An invariable pendulum with a single knife edge, however, is adequate for relative determinations. Development of Gravity Pendulums in the 19th Century Contributions from the Museum of History and Technology, Papers 34-44 On Science and Technology, Smithsonian Institution, 1966 2011-01-22T03:00:16.753Z |
