I used this book for a college course last semester and was very displeased with it. It seems like the book was rushed to print, because there are many errors. Figures are improperly dimensioned or do not reflect the information of the problem statement. At least once the book refers to a stress as a force. There are misprinteed equations within the text. For example, in one case a 3 was printed instead of an "E". In another case a "y" was printed indstead of gamma. Some of the practice problem answers given in the back of the book are incorrect. In the tables listing the dimensions and properties of American standard steel W-shapes, the columns for web thickness, flange thickness and flange width are mislabeled. In the table giving useful properties of areas, the moment of inertia for a thin tube is incorrect as is the location of the centroid of half of a thin tube. One of the less serious, but more glaring errors occurs in chapter twelve. The chapter is titled "Yield and Fructure Criteria" instead of "Yield and Fracture Criteria". This incorrect title is repeated on every page of the chapter. This reveals the quality of editing for this edition of Popov's book.
