Mechanical Vibrations (eBook, ePUB)
12,76 € *
ggf. zzgl. Versand

This classic textbook by J. P. Den Hartog, retired professor of mechanical engineering at MIT, reflects the author's unique ability to combine the scholarly insight of a distinguished scientist with the practical, problem-solving orientation of an experienced industrial engineer. Although mathematics plays a role in the subject, Den Hartog employs the simplest possible mathematical approaches. His lucid explanations of complex problems are presented in a direct style and supported by illustrative models. Numerous figures in the text enhance its value as a basic foundation in a field which Den Hartog calls "a necessary tool for almost every mechanical engineer." The author examines such topics as the kinematics of vibration (including harmonic motions and non-harmonic periodic motions), degrees of freedom, gyroscopic effects, relaxation oscillations, Rayleigh's method, natural frequencies of torsional vibration, Karman vortices, and systems with variable elasticity. Drawing on his experience as an engineer in private industry and in the U.S. Navy's Bureau of Ships, Den Hartog applies theory to practice, discussing the effects of vibrations on turbines, electrical machines, helicopter rotors and airplane wings, diesel engines and electrical transmission lines.As a special aid to classroom work or self-study, this practical text includes an extensive selection of 233 problems and answers that test the student's mastery of every section of the book. In addition, a highly useful Appendix contains "A Collection of Formulas" for determining the load per inch deflection of linear springs, the load per radian rotation of rotational springs, the natural frequencies of simple systems, the longitudinal and torsional vibration of uniform beams, the transverse or bending vibrations of uniform beams, and the vibrations of rings, membranes, and plates.When Mechanical Vibrations was first published in 1934, it was a pioneering work in a field which had just been introduced in America's technical schools. In fact, the author wrote it to assist him in teaching the subject at Harvard. "During the life of the book," he says, "from 1934 on, the art and science of engineering has grown at an astonishing rate and the subject of vibration has expanded with it." Professor Den Hartog's constant revisions have kept his book at the forefront of this vital subject, as useful today as its earlier versions were to students of the past.

GM New Look Bus
45,00 € *
ggf. zzgl. Versand

The GM New Look bus (nicknamed "Fishbowl" for its six-piece rounded windshield) is a transit bus introduced in 1959 by General Motors and produced until 1986. Like GM's over-the- road buses, including the Greyhound Scenicruiser, the air- sprung New Look did not have a traditional ladder frame. Instead it used an airplane-like stressed-skin construction in which an aluminum riveted skin supported the weight of the bus. The wooden floor kept the bus' shape. The engine cradle was hung off the back of the roof. As a result, the GM New Look weighed significantly less than competitors' city buses. The design is listed as U.S. Patent D182,998 by Roland E. Gegoux and William P. Strong. 44,484 New Look buses were built over the production lifespan, of which 33,413 were built in the U.S. and 11,071 were built in Canada (GM Diesel Division). Separated by general type, the production figures comprised 510 29-foot city buses (all U.S.-built), 9,355 35-foot city buses (7,804 U.S.-built, 1,551 Canadian), 31,348 40-foot city buses (22,034 U.S., 9,314 Canadian) and 3,271 suburban coaches (of which only 206 were built in Canada).

Using Fuel Cells to Reduce Mobile Source Emissions
79,00 € *

Currently large numbers of transport trucks idle during times when they are not actively transporting a load. The amount of fuel used and emissions produced during this time of inactivity is not insignificant. Due to the amounts of harmful emissions created by idling diesel trucks, interest has been growing in using fuel cell powered auxiliary power units (APUs) to reduce idling in line-haul trucks resulting in a handful of states instituting idling bans, with many more considering anti-idling legislation. Another example of a diesel transport diesel emission source is the Transport Refrigeration Unit, or TRU. The TRU is used to provide refrigerated space during the transport of a many important commercial products. TRUs are used in all modes of transport, on rail cars, on ocean going shipping containers, over the road truck trailers and even on airplane Unit Load Devices. This paper examines the impact of emissions from small mobile source diesel engines and details the design, construction and performance of both a fuel cell powered APU and a fuel cell powered TRU.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact.

O. Winston Link: Life Along the Line
52,90 CHF *
ggf. zzgl. Versand

O. Winston Link is America's most celebrated railroad photographer. Link began photographing the Norfolk and Western, the last major steam railroad in the United States, in the mid-1950s, when the N&W was converting its operations from steam to diesel. Link's N&W project captured the railroad industry at a moment of transition, before the triumph of the automobile and the airplane that ended passenger service on the line and before the corresponding dramatic reduction in the workforce. And, just as importantly, Link's work reveals a small-town way of life that was about to experience seismic shifts and in many cases vanish completely. The images in O. Winston Link: Life Along the Line focus on the people and communities surrounding the railroad, in particular recording life in the Appalachian portion of the Norfolk & Western’s service area. The book is published in cooperation with the O. Winston Link Museum in Roanoke, Virginia, which holds the complete archive of Link's N&W project. It replaces two previous Abrams books on Link, Steam, Steel & Stars and The Last Steam Railroad in America. O. Winston Link: Life Along the Line offers a broad view of the entire range of Link’s portfolio of the last years of the Norfolk and Western in steam, including excellent examples of both the keystone work and of the photographs, such as modernist images, that have not been previously published.
