Not flash cards . The content is good, but these aren't actually flash cards. It's a bound book with very thin pages and two words to each page. Studying with flashcards is best done by testing one's self with cards, slipping failures back into the deck for near-term review, and setting repeated successes aside. This isn't possible with a book.

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

Same old coverage . I was sorely disappointed in this book. I went by other reader's recommendations and I'm at a loss as to why it's got a 5-star rating. I was, and still am, looking for a source that will get past the theory & history and describe how to complete the process: What do you do after you've baselined & have to produce a build
