Detailed Mechanical Design:A Practical Guide James G. Skakoon
The primary emphasis of this book is the modeling, analysis, and control of mechanical systems. The methods and results presented can be applied to a large class of mechanical control systems, including applications in robotics, autonomous vehicle control, and multi-body systems. The book is unique in that it presents a unified, rather than an inclusive, treatment of control theory for mechanical systems. A distinctive feature of the presentation is its reliance on techniques from differential and Riemannian geometry. The book contains extensive examples and exercises, and will be suitable for a growing number of courses in this area. It begins with the detailed mathematical background, proceeding through innovative approaches to physical modeling, analysis, and design techniques. Numerous examples illustrate the proposed methods and results, while the many exercises test basic knowledge and introduce topics not covered in the main body of the text. The audience of this book consists of two groups. The first group is comprised of graduate students in engineering or mathematical sciences who wish to learn the basics of geometric mechanics, nonlinear control theory, and control theory for mechanical systems. Readers will be able to immediately begin exploring the research literature on these subjects. The second group consists of researchers in mechanics and control theory. Nonlinear control theoreticians will find explicit links between concepts in geometric mechanics and nonlinear control theory. Researchers in mechanics will find an overview of topics in control theory that have relevance to mechanics.

This comprehensive text examines both global and local coronary blood flow based on morphometry and mechanical properties of the coronary vasculature. Using a biomechanical approach, this book addresses coronary circulation in a quantitative manner based on models rooted in experimental data that account for the various physical determinants of coronary blood flow including myocardial-vessel interactions and various mechanisms of autoregulation. This is the first text dedicated to a distributive analysis (as opposed to lumped) and provides digital files for detailed anatomical data (e.g., diameters, lengths, node-to-node connections) of the coronary vessels. This book also provides appendices with specific mathematical formulations for the biomechanical analyses and models in the text. Written by Dr. Ghassan S. Kassab, a leader in the field of coronary biomechanics, Coronary Circulation: Anatomy, Mechanical Properties, and Biomechanics is a synthesis of seminal topics in the field and is intended for clinicians, bioengineers, and researchers as a compendium on the topic. The detailed anatomical and mechanical data provided are intended to be used as a platform to address new questions in this exciting and clinically very important research area.

The idea of engineering has been present since prehistoric times when humans started shaping important creations like the lever, wheel and pulley. Every invention is described with the contemporary explanation of basic engineering principles of mechanics. The word engineering has been derived from the term engineer and dates back to around recently 1325 and the word engineer in those times meant or denoted to someone who was the constructor of engines. The term engine has actually become obsolete as it is now refers to a military machine or in a more detailed description it was a mechanical apparatus used in wars. The word engine comes from the Latin word ingenium which means intrinsic quality, particularly cerebral power, as in an ingenious creation. As time passed more structures like houses, buildings and bridges were invented, which required new engineering techniques. The term civil engineering was introduced to differentiate among those who were experts in building military machines and was called military engineering. The term engineering is extremely broad and comprises a variety of different types of engineering, each focusing on specific parts of technology, applied science and applications. 1.

Student design engineers often require a "e;cookbook"e; approach to solving certain problems in mechanical engineering. With this focus on providing simplified information that is easy to retrieve, retired mechanical design engineer Keith L. Richards has written Design Engineer´s Handbook.This book conveys the author´s insights from his decades of experience in fields ranging from machine tools to aerospace. Sharing the vast knowledge and experience that has served him well in his own career, this book is specifically aimed at the student design engineer who has left full- or part-time academic studies and requires a handy reference handbook to use in practice. Full of material often left out of many academic references, this book includes important in-depth coverage of key topics, such as:Effects of fatigue and fracture in catastrophic failuresLugs and shear pinsHelical compression springsThick-walled or compound cylindersCam and follower designBeams and torsionLimits and fits and gear systemsUse of Mohr´s circle in both analytical and experimental stress analysis This guide has been written not to replace established primary reference books but to provide a secondary handbook that gives student designers additional guidance. Helping readers determine the most efficiently designed and cost-effective solutions to a variety of engineering problems, this book offers a wealth of tables, graphs, and detailed design examples that will benefit new mechanical engineers from all walks.
