analysis and design of machine elements pdf

Such organization emphasizes the importance of safety in machine element design, helps students who may have had little exposure to machines, structures or industrial practice to build a clear structure of the course and to link analysis with design. Design requires extensive use of knowledge in mechanical engineering science, such as mechanical drawing, materials properties, statics and dynamics, mechanics of materials, synthesis and analysis of mechanisms and machines, manufacturing processes, geometric dimensioning and tolerancing, fluid mechanics, computer-aided design and so on.

Fundamentals necessary for the entire book are introduced in Part I, others required for specific machine elements are embedded in relevant chapters. For example, tribology and fluid mechanics are introduced in the chapter on sliding bearings. Such an arrangement helps students effectively bridge the gap between basic scientific knowledge and design activity, assist their better understanding of complex working mechanism of machine elements and ultimately promote their engineering and innovation capability in mechanical design.

This book provides general methodology and fundamentals for the analysis and design
of common machine elements, with an aim to help students gain competence in applying these methods and procedures to machine element design.When designing machine elements for important applications, designers should check all important data from standards, design handbooks or industrial manuals.The book uses the International System of Units, with conversion to other unit systems introduced.

The book evolved from lecture notes initially prepared for international undergraduates in a mechanical design course, with a hope to increase the competency of mechanical engineering graduates to function well in a globalized profession and to help them communicate effectively and
cooperate productively in international collaborative design activities. Although the author has made every effort to ensure accuracy and conformity with good engineering practice, errors are unavoidable and constructive suggestions and feedback are warmly welcomed.
