The Mechanism of Solid Viscosity, written by Carl Barus and published in 1892, is a scientific treatise that explores the nature and behavior of solid materials under stress. Barus, a noted physicist and engineer, draws on his extensive research and experimentation to present a detailed analysis of the physical properties of solids, focusing particularly on their viscosity and elasticity.The book begins with an overview of the basic principles of mechanics and thermodynamics, providing a foundation for understanding the behavior of solids under stress. Barus then delves into the specifics of solid viscosity, examining the ways in which materials respond to various types of stress and strain. He also explores the role of temperature and pressure in determining the viscosity of solids, and discusses the ways in which different types of materials exhibit different degrees of viscosity.Throughout the book, Barus uses a combination of theoretical analysis and experimental data to support his arguments and conclusions. He presents numerous examples of real-world materials and situations, ranging from the behavior of metals under high pressure to the flow of molten lava, in order to illustrate the principles he is discussing.Overall, The Mechanism of Solid Viscosity is a comprehensive and detailed exploration of a fundamental aspect of material science. It provides a valuable resource for anyone interested in the mechanics of solids, and remains a significant contribution to the field more than a century after its initial publication.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
