Description
Description
Mechanical Design Engineering Handbook, Third Edition discusses the mechanical engineering skills that are essential to power generation, production, and transportation. Machine elements such as bearings, shafts, gears, belts, chains, clutches and belts represent fundamental building blocks for a wide range of technology applications. The aim of this handbook is to present an overview of the design process and to introduce the technology and selection of specific machine elements that are fundamental to a wide range of mechanical engineering design applications.
This book includes detailed worked examples for the design and application of machine elements and over 600 images, with line drawings complemented by solid model illustrations to aid understanding of the machine elements and assemblies concerned. The context for engineering and mechanical design is introduced in the first chapter, which also presents a blended design process, incorporating principles from systematic and holistic design, as well as practical project management.

Marc Masen
Dr Marc Masen is Reader in Tribology and Mechanical Engineering Design in the
Department of Mechanical Engineering, Imperial College London. He is the Academic
Lead in Mechanical Engineering Design. His expertise includes the response of materials to
mechanical contact and interaction, with a special focus on materials showing non
linear and complex behaviour; such as polymers, elastomers, greases, and biological
tissue. He designs, builds, and adapts advanced tribometers to gain new insights into
the behaviour of these materials. Within the Tribology research group, he collaborates
closely with a range of companies, including SMEs and multinationals such as L'Oréal,
Shell and SKF. He is the co-editor of the journal Biotribology and sits on the editorial
board of Proceedings of the Institution of Mechanical Engineers Part J - Journal of
Engineering Tribology. He teaches on a range of modules, including Mechanical
Transmissions, focusing on machine elements such as shafts, gears, bearings and
couplings.
