Book excerpt: Excerpt from A Description of Nbs Calibration Services in Mechanical Vibration and Shock There are two principal categories of measurement used in the calibration of accelerometers and reference exciters at the National Bureau of Standards: comparison and absolute. When the calibration factor is obtained directly from a measurement of quantities which form the base units of a system of units, the calibration is called absolute The comparison method involves simultaneous measurement of the outputs of the transducer under test and a reference transducer of known and stable characteristics, with both devices subject to the same excitation. The comparison method has been implemented by constructing a vibration exciter with a built-in or attached transducer and a space for mounting an accelerometer to be tested. A test accelerometer can be readily calibrated by direct comparison of its voltage to that of a standard. The comparison method is very simple and relatively inexpensive, compared to the absolute methods of calibration, which can be very time consuming. This survey document describes the methods of calibrating vibration pickups by comparison with nbs standards, including a special shock calibration service, and absolute methods used primarily in the calibration of the reference standards. A summary is given of the various calibration procedures, beginning with the comparison calibration procedures using electrodynamic, air-bearing, and piezoelectric exciters which cover the low, mid, and high-frequency ranges, respectively. A shock calibration service which employs analog-to-digital converters and fast Fourier transform analysis to calibrate a test accelerometer in terms of a reference accelerometer is then described. The last section describes the absolute calibration procedures which are primarily used to calibrate the reference exciters and accelerometers.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Precision Measurement and Calibration: Selected Nbs Papers on Mechanics Some of the papers in Handbook 77 are still useful, but new theoretical knowledge, improved materials, and increasingly complex experimental techniques have so advanced the art and science of measurement that 'a new compilation has become necessary. The present volume is part of a new reprint collection, designated nbs Special Publication 300, which has been planned to fill this need. Besides previously published papers by the nbs staff, the collection includes selected abstracts by both nbs and non-nbs authors. It is hoped that SP 300 will serve both as.a textbook and as a reference source for the many scientists and engineers who fill responsible positions in standards laboratories.

Download or read book Foundations of Mechanical Accuracy written by Wayne and published by . This book was released on 1971-05-15 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his introduction to this book, George R. Harrison, Dean Emeritus of M.I.T.'s School of Science, writes as follows: "Basic to man's behavior is his ability to determine, modify, and adapt to his environment. This he has been able to do in proportion to his skill at making measurements, and fundamental to all other measuring operations is his ability to determine locations in the material world. Thus the science of mechanical measurements is a fundamental one. It is this science, and the art which accompanies and informs it, with which this book is concerned." This is the third book produced by the , Inc., of Bridgeport, Connecticut. Like all of its products, the book is marked by a clean precision of design and execution. The firm has built a worldwide reputation since 1924, both as a manufacturer of special tooling to extremely close accuracies and of machine tools that make possible a very high degree of precision. Wayne R. Moore has assembled in the 350 pages of Foundations of Mechanical Accuracythe company's intimate knowledge of and experience with mechanical accuracy, and how to achieve it. He has illustrated his text with over 500 original photographs and drawings. This book tells how to attain precision in manufacturing to millionths of an inch and how to control such precision by appropriate measuring techniques. The book is divided into four main sections: geometry, standards of length, dividing the circle, and roundness. A fifth section covers "Universal Measuring Machine Techniques and Applications." The book is printed in two colors throughout, and interspersed with full-page, full-color plates.

This book was released on 2001-10-30 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Established by Congress in 1901, the National Bureau of Standards (NBS), now the National Institute of Standards and Technology (NIST), has a long and distinguished history as the custodian and disseminator of the United States' standards of physical measurement. Having reached its centennial anniversary, the NBS/NIST reflects on and celebrates its first century with this book describing some of its seminal contributions to science and technology. Within these pages are 102 vignettes that describe some of the Institute's classic publications. Each vignette relates the context in which the publication appeared, its impact on science, technology, and the general public, and brief details about the lives and work of the authors. The groundbreaking works depicted include: A breakthrough paper on laser-cooling of atoms below the Doppler limit, which led to the award of the 1997 Nobel Prize for Physics to William D. Phillips The official report on the development of the radio proximity fuse, one of the most important new weapons of World War II The 1932 paper reporting the discovery of deuterium in experiments that led to Harold Urey's1934 Nobel Prize for Chemistry A review of the development of the SEAC, the first digital computer to employ stored programs and the first to process images in digital form The first paper demonstrating that parity is not conserved in nuclear physics, a result that shattered a fundamental concept of theoretical physics and led to a Nobel Prize for T.

Download or read book Ignition written by John Drury Clark and published by Rutgers University Press. This book was released on 2018-05-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly reissued debut book in the Rutgers University Press Classics Imprint is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.
