Shigley's Mechanical Engineering Design is intended for students beginning the study of mechanical engineering design. Students will find that the text inherently directs them into familiarity with both the basics of design decisions and the standards of industrial components. It combines the straightforward focus on fundamentals that instructors have come to expect, with a modern emphasis on design and new applications. The tenth edition maintains the well-designed approach that has made this book the standard in machine design for nearly 50 years. Specific statistical material pertinent to the 10th edition was retained and integrated within the sections that utilize statistics. A few examples are: The mathematical relationship between the design factor and reliability is covered in the first chapter of Introduction to Mechanical Design where the design factor and reliability are defined and discussed. In Sec. 2-2, The Statistical Significance of Material Properties, is totally self-contained. The statistical Weibull distribution is necessary in the chapter on Rolling-Contact Bearings and is completely contained within this chapter.
