The book Engineering Mechanics Statics 12th edition by R.C. Hibbeler is another proof that publishers and authors and everyone else involved; only concerns are making money. Its a pretty book in full color with plenty of pictures some useful nearly all of them under explained. one out of ten examples may be useful to the stundent for solving the hw problems, these examples are to few and not in an amount of detail that they should be. all in all there are two many words in this book to be for engineering, and not enough well layed out mathmatical explanition that is directly usable for homework understanding. My advice is if you are "required" to purchase this book for class, don't do it; instead copy the hw problems by some means (torrent, friend, etc.) take good notes in class, if your teacher is any good, and look online for example problems theres lots of them.
