As part of your review you may want to check Mechanical Engineering Reference Manual for the PE Exam, 12th Edition Hardcover, Michael R Lindeburg

The Mechanical PE exam is 8 hours long, divided into two 4-hour long sessions (morning and afternoon). The Mechanical PE exam morning session is the same for all Mechanical PE examinees, and consists of 40 multiple-choice problems drawn from all areas of Mechanical engineering. In the afternoon, you work one of three depth exam sections: HVAC and Refrigeration, Mechanical Systems and Materials, or Thermal and Fluids Systems. Each depth section consists of 40 multiple-choice problems that gauge your knowledge of the topics specified. You are required to choose your afternoon exam section when you register for the Mechanical PE exam.

So to all Mechanical PE examinees good luck.

Shigley’s Mechanical Engineering Design
Publisher: McGraw-Hill Science/Engineering/Math | 2006-10-25 | ISBN:0073312606 | Pages:1059 | PDF | 5.5 MB

Book Description:

The eighth edition of Shigley’s Mechanical Engineering Design maintains the basic approaches that have made this book the standard in machine design for over 40 years. At the same time it combines the straightforward focus on fundamentals instructors have come to expect with a modern emphasis on design and new applications. Overall coverage of basic concepts are clear and concise so that readers can easily navigate key topics. This edition includes a new case study to help illuminate the complexities of shafts and axles and a new finite elements chapter. Problem sets have been improved, with new problems added to help students progressively work through them. The book website includes ARIS, which is a homework management system that will have 90 algorithmic problems.

The method is most often used for composite materials such as reinforced thermosetting resins or to determine how much a resin or plastic has cured. The test complements the measurement of glass transition temperature, as an indirect measure of the degree of cure of a composite. It is inexpensive and quick, and provides information on the cure throughout a part.
