- conciseness: It doesn't spend pages trying to tell you ΣF=0
- example problems: the examples actually show a variety of scenarios, and not just the ones where they practically give you 3 out of the 4 variables in an equation.
- problem sets: good range of difficulty; plenty to practice with
- problem answers: basically 3/4 of all the problems in the book have answers in the back. if the problem number is divisible by 4, it's not there.
- fundamental problem solutions: partial solutions to all fundamental problems are in the back. Even though they're not explicitly step-by-step, they're not bad. Plus the fundamental problems aren't that hard to begin with.
-weird notation and variable names: like for work-energy, Hibbeler uses T for kinetic energy for some reason. .
-The actual principles explained in this edition(you know, the actual statics and dynamics?) haven't changed since the previous edition, or the one before that... or the one before that one. Come to think of it, how much of earth's physics has been drastically altered in the past 3 years? not much, if anything at all. But for some reason authors are still compelled to push out a new round of physics, calculus and engineering books. (ok seriously? Calculus hasn't changed since my grandfather studied it in college.) Apparently our cranes and structures are in danger of flying into the sky, so now you'll have to buy this super awesome newly improved edition only to find out that it tells you the exact same thing the 12th edition did. But you won't know that until you spent $200 and opened the packaging.
Ranting aside... is it a good book? yeah definitely. It's probably one of the best textbooks I have, and I'll keep it after I graduate and for as long as I'm in the engineering world. But is it necessary to put out a new edition every 2-3 yrs and get professors all excited and force their students to buy it? no. See if you can convince your professor to let you buy an older edition for much much cheaper, especially if s/he uses mastering engineering.
**If your prof doesn't use Mastering Engineering, keep in mind though, that the end-of-section problems in older editions are in a different order, and there are some new problems in here that weren't in previous editions.**
(Then again, you can still buy an older version and just ask somebody with this edition to see if he'll let you take a picture of the exercise sets in his book. Problem solved.)
