A comprehensive text and reference for a first study of system dynamics and control, this volume emphasizes engineering concepts -- modeling, dynamics feedback, and stability, for example -- rather than mechanistic analysis procedures designed to yield routine answers to programmable problems. Its focus on physical modeling cultivates an appreciation for the breadth of dynamic systems without resorting to analogous electric-circuit formulation and analysis.
After a careful treatment of the modeling of physical systems in several media and the derivation of the differential equations of motion, the text determines the physical behavior those equations connote: the free and forced motions of elementary systems and compound "systems of systems." Dynamic stability and natural behavior receive comprehensive linear treatment, and concluding chapters examine response to continuing and abrupt forcing inputs and present a fundamental treatment of analysis and synthesis of feedback control systems. This text's breadth is further realized through a series of examples and problems that develop physical insight in the best traditions of modern engineering and lead students into richer technical ground.
As presented in this book, the concept of dynamics forms the basis for understanding not only physical devices, but also systems in such fields as management and transportation. Indeed, the fundamentals developed here constitute the common language of engineering, making this text applicable to a wide variety of undergraduate and graduate courses. 334 figures. 12 tables.

The Porsche 959 is regarded as one of the most exceptional vehicles in automotive history It won the murderous Paris-Dakar rally, prevailed in Le Mans as the first all-wheel drive racer against racers with more PS and delighted its customers with road performances never seen before A fascinating boxed set with three volumes on different topics: technical data, history, and a large-format illustrated book that shows the 959 genesis including all derivatives and new photos of the most beautiful specimen To the present day, the Porsche 959 is regarded as one of the most exceptional vehicles in automotive history: a technical marvel with its all-wheel drive, a refined biturbo engine, 450 PS and a top speed of 315 km/h - still breathtaking 30 years after its first roll-out. The idea behind this tour de force was to build a Porsche that fitted the new Group B regulations just established in 1983: the Group B Porsche. The regulations demanded just 200 vehicles for the homologation, that is why Porsche was able to turn the technological knowledge of that time into a super Porsche equally suitable for the race track and for rallies - which was the intention of the new racing car series. Apart from the races, the homologation vehicles were also meant to go to private owners for the use in road traffic. The Porsche 959 excelled in all of the tasks. It won the murderous Paris-Dakar rally, prevailed in Le Mans as the first all-wheel drive racer against racers with more PS and delighted its customers with road performances never seen before. The surprising end of the Group B regulations, enforced by the motorsports authorities after deadly accidents at the World Rally Championship, ended the motorsports career of the 959 before it had really begun. But the about 300 vehicles that were built, still tell the story of a fascinating car that became a celebrated and precious icon over the last years. J rgen Lewandowski witnessed the development of the Porsche 959 more than 30 years ago and describes the difficult birth of the super car including the three Paris-Dakar rallies and the Le Mans race. A fascinating boxed set with three volumes on different topics: technical data, history, and a large-format illustrated book that shows the 959 genesis including all derivatives and new photos of the most beautiful specimen. After 30 years, this comprehensive work presents even the minutest details, it comments on events in the past, and contemporary witnesses have their say - all in all it is a literary monument to the Porsche 959.
We live with travel delays on congested roads, shipping delays on clogged railways, and delays on repairs and project approvals due to gridlocked leadership. And when we can't move, when goods are delayed, and when information networks can't connect, then economic opportunity deteriorates and social inequity grows. We don't have to take it anymore! In Move, Harvard Business School professor and bestselling author Rosabeth Moss Kanter visits the business leaders, mayors, transportation advocates, and entrepreneurs across the country tackling these challenges through underwater tunnels, instant bridges, road sensors, parking apps, bike-sharing programs, seamless wifi, and much more. It all adds up to a new vision for American mobility, where local leaders and public-private partnerships lead the way. With unique insight and unrivaled expertise, Kanter gives us a sweeping look at the innovative projects, vital leaders, and bold solutions that are moving our transportation infrastructure toward a cleaner, faster, and more prosperous future.
A selection of 19 articles (most) first published in American Scientist by the engineer/author notable for his interest in giving engineers a broader sense of their field, and giving the general public an appreciation of the art and science of engineering. Among Petroski's previous works are The Evolution of Useful Things and To Engineer Is Human . Annotation c. by Book News, Inc., Portland, Or.
Firebrand conservative columnist, commentator, Internet entrepreneur, and #1 New York Times bestselling author Michelle Malkin tells the fascinating, little-known stories of the inventors who have contributed to American exceptionalism and technological progress.In July 2012, President Obama infamously proclaimed: "If you've got a business--you didn't build that. Somebody else made that happen." Malkin wholeheartedly disagrees. Who Built That is a rousing tribute to the hidden American capitalists who pioneered everyday inventions. They're the little big things we take for granted: bottle caps and glassware, tissue paper, flashlights, railroad signals, bridge cables, revolutionary plastics, and more. Malkin takes readers on an eclectic journey of American capitalism, from the colonial period to the Industrial Age to the present, spotlighting awe-inspiring and little-known "tinkerpreneurs" who achieved their dreams of doing well by doing good. You'll learn how famous patent holders Abraham Lincoln and Mark Twain championed the nation's unique system of intellectual property rights; how glass manufacturing mavericks Edward Libbey and Mike Owens defied naysayers to revolutionize food, beverage, and pharmaceutical packaging; how penniless Croatian immigrant Anthony Maglica started his $400 million Maglite flashlight business in a rented garage; and many more riveting stories that explain our country's fertile climate for scientific advancement and entrepreneurship. To understand who we are as people, we need to first understand what motivates America's ordinary and extraordinary makers and risk-takers. Driven by her own experience as a second-generation beneficiary of the American Dream, Malkin skillfully and passionately rebuts collectivist orthodoxy to celebrate the engineers, mechanics, designers, artisans, and relentless tinkerers of all backgrounds who embody our nation's spirit of self-made entrepreneurialism.
Petroski reveals the science and engineering--not to mention the politics, egotism, and sheer magic--behind America's great bridges, particularly those constructed during the great bridge-building era starting in the 1870s and continuing through the 1930s. It is the story of the men and women who built the St. Louis, the George Washington, and the Golden Gate bridges, drawing not only on their mastery of numbers but on their gifts for persuasion and self-promotion. It is an account of triumphs and ignominious disasters (including the Tacoma Narrows Bridge, which literally twisted itself apart in a high wind). And throughout this grandly engaging book, Petroski lets us see how bridges became the "symbols and souls" of our civilization, as well as testaments to their builders' vision, ingenuity, and perseverance.
"Seamlessly linked...With astonishing scope and generosity of view, Mr. Petroski places the tradition of American bridge-building in perspective."--New York Times Book Review
The covered bridge is one of the last surviving icons of rural America. Originally designed with roof-like covers to protect the wooden support beams from the elements, the covered bridge dominated bridge design for fifty years, until the Bessemer process introduced the cheap steel which then became the material of preference. Yet these bridges over the years have been treasured for their rustic charm, romantic atmosphere (they are nicknamed "kissing bridges"), curious engineering, and historical value. Now, Historic American Covered Bridges presents a superb photographic record of 138 historic covered bridges found in the United States and Canada.
Compiled by Brian J. McKee, a leading authority on covered bridges, the book features a full color photography of each bridge, detailed truss diagrams, basic construction details, and information about the locale, including where to find the bridge. Plus, the book provides an index of the nearly 1,000 surviving covered bridges in North America. Among the featured bridges are two of the longest covered bridges left in the United States, the Medora and Williams bridges; Kentucky's Bennett Mill Bridge, the only surviving Wheeler truss bridge; and the Stark Bridge in New Hampshire, which provides one the most picturesque scenes in America. The volume also includes the Roberts Bridge, the only remaining double-barreled covered bridge in Ohio and one of only six remaining in the United States, and the Parker Bridge, which was nearly destroyed by a fire in 1991, but restored in 1992, after a fundraising drive.
Boasting 138 full-color bridge photographs and including some bridges that are more than 150 years old, Historic American Covered Bridges provides a lasting reminder of America's heritage.
First published over 40 years ago, this work has achieved the status of a classic among introductory texts on mechanics. Den Hartog is known for his lively, discursive and often witty presentations of all the fundamental material of both statics and dynamics (and considerable more advanced material) in new, original ways that provide students with insights into mechanical relationships that other books do not always succeed in conveying. On the other hand, the work is so replete with engineering applications and actual design problems that it is as valuable as a reference to the practicing engineer as it is as a text or refresher for the general engineering student.
Mechanics is not a heavy book, despite the amount of material it covers and the clarity and exactness with which it treats this material. It is undoubtedly one of the most readable texts in the field. More than 550 drawings and diagrams in the regular text and in the highly praised 112-page section of problems and answers further contribute to its lucidity and value. The emphasis is consistently on illuminating fundamental principles and in showing how they are embodied in a high number of real engineering and design problems concerning trusses, loaded cables, beams, jacks, hoists, brakes, cantilevers, springs, balances, pendulums, projectiles, cranks, linkages, propellers, turbines, fly ball engine governors, hydraulic couplings, anti-roll devices, gyroscopes, and hundreds of other mechanical systems and devices.
Chapters cover Discrete Coplanar Forces, Conditions of Equilibrium, Distributed Forces, Trusses and Cables, Beams, Friction, Space Forces, The Method of Work, Kinematics of a Point, Dynamics of a Particle, Kinematics of Plane Motion, Moments of Inertia, Dynamics of Plane Motion, Work and Energy, Impulse and Momentum, Relative Motion, and Gyroscopes. Particularly in the last two chapters, Den Hartog provides advanced material not usual in introductory texts. Very thoroughly recommended to all those anxious to improve their real understanding of the principles of mechanics. -- Mechanical World.
Index. List of equations. 334 problems, all with answers. Over 550 diagrams and drawings.
