Top critical review
Many obvious errors. Hopefully all of the errors are obvious.

This may be the only good Practice Problem Book, so take that for what it's worth. Also, haven't taken the PE exam yet.
This book is very frustrating, because many of the problems are poorly-worded or poorly diagrammed, such that the answer isn't obvious until you turn to the solution and say "WHAT?".
Some examples (FAIR USE-illustrative)
Problem 48-8. Asks you to give the term for a material whose "properties are invariant with direction", which describes an isotropic material. Except that "Isotropic" isn't one of the answers given. So you turn to the solution, which says "An Anisotropic material looks and behaves the same in every direction." Which is exactly opposite of what an anisotropic material is.
Problem 51-6 has you finding the thermally-induced tensile stress in a steel bolt that's holding a steel flange to an aluminum flange. The thermal growth of the aluminum is greater than the steel, which puts the bolt into tension. The problem statement gives you the CTE for steel and aluminum, but they're the same, which means that there's no thermally induced stress at all. So you turn to the solution and find that you can find a nonzero thermally induced stress if you use the correct CTE for aluminum.
Problem 51-10 wants you to look at a beam in compression, and then find the normal stress out of the beam, based upon the compressive axial load and an applied shear at the section of interest. Basically, it's asking you to combine the shear in a plane with a stress that's normal to that plane, which is physically impossible. So you turn to the solution and it seems that whoever solved the problem didn't read it because he arbitrarily decided that the stress was in plane. Which is physically meaningful, but not what was put explicitly into the problem statement.
So if you are willing to go to their classes and get the errata (I hope there's errata!), or print errata off their website, or just hope that you find all the errors this is a great book. If this is the only practice problems book, then it's adequate.
