PPI PE Mechanical Engineering Machine Design and Materials Practice Exam, 2nd Edition – A Comprehensive Practice Exam for the NCEES PE Mechanical Machine Design & Materials Exam

Amazon has this down to a science, the book is a great aid for the PE license

Using this practice exam along with the NCEES practice exam and the 6-minute problems book to gauge my preparedness and practice for the PE exam. I'm only 20 questions into the exam and already have run into at least 3 problems where data given in the prompt directly conflicts with values used in the solutions.For these problems I couldn't come up with any of the answers provided, so had to go check the solution, only to find that I was doing the problems correctly but with different numbers.It looks like for the 2nd edition they were trying to improve some of the questions and didn't do a good job of carrying the changes over through the solutions and answers. It's a shame because this book could be a useful studying tool but a book of exam questions loaded with errors is almost useless...

Book came in perfect condition and was exactly what we needed. No complaints.
