This book is comprehensive, convenient, detailed, and is a guide for the mechanical engineer. It aids the reader in understanding the basics of a wide variety of important engineering subjects. With the help of the methodology laid forth in this book, designers will be able to narrow down their options to those that are the most suitable for their projects. It’s one of a kind because of how the material inside it is organised; the user gets quick access to information, and they have a lot of leeway to explore the possibilities available to them. Even more customization is possible since the procedure is also implemented as software. In addition to this, the book is meant to serve as a long-term reference source. This methodology, together with the accompanying charts and tables of performance indices, may be used to real-world challenges involving the choice of materials and processes, and the library of “useful solutions” is especially valuable in modelling, an important aspect of optimum design. Starting with the material indices produced in the case studies of the text, the reader may go to the modelling of new design challenges, leading to new material indices and value functions, and new, potentially innovative, choices of material, as his or her expertise increases. It is assumed throughout the book that the reader has a foundation in fundamental engineering science, material science, manufacturing processes, and engineering economics in order to construct any remotely realistic design. Thus, this book is aimed towards upper-level undergraduates, graduate students, and professional engineers who have never taken a course on the mechanical design process.
