Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of. | Mechatronics SOLID MECHANICS AND ITS APPLICATIONS Volume 136 Series Editor . GLADWELL Department of Civil Engineering University of Waterloo Waterloo Ontario Canada N2L 3GI Aims and Scope of the Series The fundamental questions arising in mechanics are Why How and How much The aim of this series is to provide lucid accounts written by authoritative researchers giving vision and insight in answering these questions on the subject of mechanics as it relates to solids. The scope of the series covers the entire spectrum of solid mechanics. Thus it includes the foundation of mechanics variational formulations computational mechanics statics kinematics and dynamics of rigid and elastic bodies vibrations of solids and structures dynamical systems and chaos the theories of elasticity plasticity and viscoelasticity composite materials rods beams shells and membranes structural control and stability soils rocks and geomechanics fracture tribology experimental mechanics biomechanics and machine design. The median level of presentation is the first year graduate student. Some texts are monographs defining the current state of the field others are accessible to final year undergraduates but essentially the emphasis is on readability and clarity.
