A History Of Suspension Bridges In Bibliographical Form

The annual collections in the History of Technology series look at the history of technological discovery and change, exploring the relationship of technology to other aspects of life and showing how technological development is affected by the society in which it occurred.

Strength of materials is that branch of engineering concerned with the deformation and disruption of solids when forces other than changes in position or equilibrium are acting upon them. The development of our understanding of the strength of materials has enabled engineers to establish the forces which can safely be imposed on structure or components, or to choose materials appropriate to the necessary dimensions of structures and components which have to withstand given loads without suffering effects deleterious to their proper functioning. This excellent historical survey of the strength of materials with many references to the theories of elasticity and structures is based on an extensive series of lectures delivered by the author at Stanford University, Palo Alto, California. Timoshenko explores the early roots of the discipline from the great monuments and pyramids of ancient Egypt through the temples, roads, and fortifications of ancient Greece and Rome. The author fixes the formal beginning of the modern science of the strength of materials with the publications of Galileo's book, "Two Sciences," and traces the rise and development as well as industrial and commercial applications of the fledgling science from the seventeenth century through the twentieth century. Timoshenko fleshes out the bare bones of mathematical theory with lucid demonstrations of important equations and brief biographies of highly influential mathematicians, including: Euler, Lagrange, Navier, Thomas Young, Saint-Venant, Franz Neumann, Maxwell, Kelvin, Rayleigh, Klein, Prandtl, and many others. These theories, equations, and biographies are further enhanced by clear discussions of the development of engineering and engineering education in Italy, France, Germany, England, and elsewhere. 245 figures.

This book deals with the period when iron became the dominant ’high-technology’ material, increasingly taking over from timber and masonry. It was necessary for the engines and machines of the new industries, but equally vital for the vast civil engineering works which supported this industrialisation. It was these works - mills, warehouses, dockyards, and above all bridges - which so impressed the public in the early 19th century. The papers selected here trace the evolving structural uses of cast and wrought iron in frames and roofs for buildings, and look in particular at the development of bridge design and construction, in America, France, and Russia, as well as in Britain. They cover the processes of design and testing, and at the same time throw much light on the attitudes and careers of the engineers themselves.

This book provides an historical perspective for modern tensile architecture in the 20th century. It explores the tents of nomad cultures, geographical distribution of tent types, the effect of the dromedary on the distribution of the black tent, and seasonal specialization of Eskimo dwellings.
