Unsuitable for undergraduates . The original Mechanical Engineering Design book written by Joseph Shigley, and later, with Larry Mitchell, was an excellent undergraduate text; it was readable at the introductory level, and it contained enough information and methodology for use as a good reference book after graduation.  Unfortunately, this revised text, which was rewritten by Charles Mischke, is thoroughly unreadable, obfuscating, and is totally unsuitable as a text for undergraduate mechanical engineering students.  The book is full of nuances, subtleties and informative data that do make it useful as a reference book on the shelf of an experienced design engineer, but not as a text for students learning the subject.  For those who plan to teach a course for mechanical engineering majors on this topic, I recommend other texts such a Jack Collins' Mechanical Design of Machine Elements and Machines, Wiley, 2003

why a classic? . I figured if Oprah wanted America to read this book that it couldn't be too bad. I had held out on reading Faulkner, and now I know why. I read alot and love reading but this book, and "As I Lay Dying" makes me question why oh why Faulkner is a classic. My hypothesis is that its so unapproachable therefore people think it must be brilliant. This is a good book for english class when you can sit around and discuss the meanings of it all and read sparknotes together. This is not a book for sitting at home and reading for yourself. If you want to know the story just go read the sparknotes version. The book itself is too hard to figure out and there is little plot. its just a long headache really.

Poor Condition . I was very disappointed in the condition of the book.  The book worked fine for what I wanted it for but I had to clean it up before I could use it.  There was food stuff all over it.  The pages were not only dirty but roughed up on the edges.  I felt like I paid too much for the condition it was in
