Download or read book The Wheel written by Richard W. Bulliet and published by Columbia University Press. This book was released on 2016-01-19 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, Richard W. Bulliet focuses on three major phases in the evolution of the wheel and their relationship to the needs and ambitions of human society. He begins in 4000 B.C.E. with the first wheels affixed to axles. He then follows with the innovation of wheels turning independently on their axles and concludes five thousand years later with the caster, a single rotating and pivoting wheel. Bulliet's most interesting finding is that a simple desire to move things from place to place did not drive the wheel's development. If that were the case, the wheel could have been invented at any time almost anywhere in the world. By dividing the history of this technology into three conceptual phases and focusing on the specific men, women, and societies that brought it about, Bulliet expands the social, economic, and political significance of a tool we only partially understand. He underscores the role of gender, combat, and competition in the design and manufacture of wheels, adding vivid imagery to illustrate each stage of their development.

Download or read book March 1917 written by Aleksandr Solzhenitsyn and published by University of Notre Dame Pess. This book was released on 2021-10-15 with total page 1122 pages. Available in PDF, EPUB and Kindle. Book excerpt: In March 1917, Book 3 the forces of revolutionary disintegration spread out from Petrograd all the way to the front lines of World War I, presaging Russia’s collapse. One of the masterpieces of world literature, The Red Wheel is Nobel prize–winner Aleksandr Solzhenitsyn’s multivolume epic work about the Russian Revolution told in the form of a historical novel. March 1917—the third node—tells the story, day by day, of the Russian Revolution itself. Until recently, the final two nodes have been unavailable in English. The publication of Book 1 of March 1917 (in 2017) and Book 2 (in 2019) has begun to rectify this situation. The action of Book 3 (out of four) is set during March 16–22, 1917. In Book 3, the Romanov dynasty ends and the revolution starts to roll out from Petrograd toward Moscow and the Russian provinces. The dethroned Emperor Nikolai II makes his farewell to the Army and is kept under guard with his family. In Petrograd, the Provisional Government and the Soviet of Workers’ and Soldiers’ Deputies continue to exercise power in parallel. The war hero Lavr Kornilov is appointed military chief of Petrograd. But the Soviet’s “Order No. 1” reaches every soldier, undermining the officer corps and shaking the Army to its foundations. Many officers, including the head of the Baltic Fleet, the progressive Admiral Nepenin, are murdered. Black Sea Fleet Admiral Kolchak holds the revolution at bay; meanwhile, Grand Duke Nikolai Nikolaevich, the emperor’s uncle, makes his way to military headquarters, naïvely thinking he will be allowed to take the Supreme Command.

Book excerpt: Drivers buy more wheels and tires for their cars and trucks than any other aftermarket accessory. This book is a comprehensive source for wheel and tire information. Whether you want to know how your wheels and tires actually work and how they affect vehicle performance, or whether you just need advice as to what best suits your vehicle, this book provides the information you are looking for. This book covers daily use and competition cars and trucks, including off-road, circle track, drag, autocross, rally, and show vehicles. Beginning with a chapter on vehicle dynamics, with explanations of center of gravity, slip angle, yaw, roll, and pitch. Author Richard Newton then moves on to general information about tires and wheels--from materials and construction to use and maintenance. He also explores how this general information applies to specific types of vehicles, using pertinent examples throughout.

Available in PDF, EPUB and Kindle. Book excerpt: Why, for many centuries, was the wheel abandoned in the Middle East in favor of the camel as a means of transport? This richly illustrated study explains this anomaly. Drawing on archaeology, art, technology, anthropology, linguistics, and camel husbandry, Bulliet explores the implications for the region's economic and social development during the Middle Ages and into modern times.

Download or read book Why the Wheel Is Round written by Steven Vogel and published by University of Chicago Press. This book was released on 2016-10-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is no part of our bodies that fully rotates—be it a wrist or ankle or arm in a shoulder socket, we are made to twist only so far. And yet there is no more fundamental human invention than the wheel—a rotational mechanism that accomplishes what our physical form cannot. Throughout history, humans have developed technologies powered by human strength, complementing the physical abilities we have while overcoming our weaknesses. Providing a unique history of the wheel and other rotational devices—like cranks, cranes, carts, and capstans—Why the Wheel Is Round examines the contraptions and tricks we have devised in order to more efficiently move—and move through—the physical world. Steven Vogel combines his engineering expertise with his remarkable curiosity about how things work to explore how wheels and other mechanisms were, until very recently, powered by the push and pull of the muscles and skeletal systems of humans and other animals. Why the Wheel Is Round explores all manner of treadwheels, hand-spikes, gears, and more, as well as how these technologies diversified into such things as hand-held drills and hurdy-gurdies. Surprisingly, a number of these devices can be built out of everyday components and materials, and Vogel’s accessible and expansive book includes instructions and models so that inspired readers can even attempt to make their own muscle-powered technologies, like trebuchets and ballista. Appealing to anyone fascinated by the history of mechanics and technology as well as to hobbyists with home workshops, Why the Wheel Is Round offers a captivating exploration of our common technological heritage based on the simple concept of rotation. From our leg muscles powering the gears of a bicycle to our hands manipulating a mouse on a roller ball, it will be impossible to overlook the amazing feats of innovation behind our daily devices.
