PROBLEM: 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

SOLUTION: NEG

PROBLEM: Short, complex, informative . I'm shocked at the negative reviews this book has received. I found it to be a brilliant introduction to an incredibly complex thinker and person. Far from bashing Jefferson for his views on blacks and women, Appleby apologizes for him, and basically agrees with her negative reviewers here that we should not judge an eighteenth century figure by twentieth century standards. Appleby has a remarkable feel for the politics of the early Republic, and does a brilliant job of recreating for a modern reader exactly what the Federalists and the Democratic-Republicans were fighting over. She makes a strong case that Jefferson stood for democracy, against elitist opponents who sought to exclude common people from voting. The core of her argument is that Jeffersonian republicanism is at the heart of our modern conception of democracy, and that both contemporary political parties -- the Democratic and the Republican -- draw equally on his legacy. An important argument to remember in these partisan times, and it gives us hope that we can overcome our current profound divisions

SOLUTION: POS

PROBLEM: Unwaiveringly BIASED and UNBALANCED . Throughout this book Mr. Shulman denigrates the contribution of the Wright Brothers. His bias is so prevalent throughout the book that I found myself shaking my head as I read blatantly contradictory statements within 5 lines of each other. The author's opinions and accusations are either based on his limited research or his intentional omission of fact. If you're even considering buying this book, I would direct you to the author's own words following a completely inane paragraph of conjecture about Orville Wright............"Or perhaps not." That about sums up this biased inaccurate ploy concealed in the history section

SOLUTION:
NEG
