Book Description

Plesha, Gray, and Costanzo’s Engineering Mechanics: Statics & Dynamics presents the fundamental concepts, clearly, in a modern context using applications and pedagogical devices that connect with today’s students.

The text features a four-part problem-solving methodology that is consistently used throughout all example problems. This methodology helps students lay out the steps necessary to correct problem-formulation and explains the steps needed to arrive at correct and realistic solutions. Once students have fully mastered the basic concepts, they are taught appropriate use of modern computational tools where applicable.

Further reinforcing the text's modern emphasis, the authors have brought engineering design considerations into selected problems where appropriate. This sensitizes students to the fact that engineering problems do not have a single answer and many different routes lead to a correct solution.

The first new mainstream text in engineering mechanics in nearly twenty years, Plesha, Gray, and Costanzo’s Engineering Mechanics: Statics and Dynamics will help your students learn this important material efficiently and effectively.

1Worst Textbook I've Had in 4 Years.
By N. Skachkov
I hate to do this two the two Penn State professors that co-authored this book, but it is without a doubt the worst textbook I've had to use in the 4 years at school. I don't know if they replaced the Hibbeler book series or not in other schools. As a point of reference I liked Hibbeler's books (at least Statics and Mechanics of Materials books that I used and kept) so if you hated them, maybe we have different expectations of what a text book should be like. The authors undoubtedly know what they are talking about, but the way they present the information is horrible. The pages are filled with equations and derivations that are completely unnecessary. The authors go into the most detailed aspect of a problem without ever really conveying the big picture. I've noticed multiple formulas boxed in and high lighted and played up like it is a generic form when it really only dealt with the specific problem discussed in the little chapter intro story (you know what I'm talking about). For example the authors go into great depths discussing the application of natural frequency, amplitude and a few other parameters of a very specific application while never really explaining their general meaning and how to recognize them. Everything seemed to be thrown at the reader at once. Different scenarios are often given for what to do in different given situation, but no attempt is made to explain why this is happening and must be done in each case. This makes all of the formulas seem random and independent of everything else and I personally can't just remember multitudes of different processes without a clear and solid logical progression from one to another.
Understand that I do have a bias which is that I am not a physics/engineering mechanics major (I'm CE) which means I'm not a huge fan of the subject. However my knowledge of physics and math did not limit me in any way at all when using this book, nor should I be considered unqualified to critique due to the fact that I'm "that guy in civil." The general concepts and the scope of their application discussed in this text are not difficult(!!) - just the way this information is presented is hard to follow and understand.

I guess its the first edition so hopefully the authors will readjust their approach a bit.
Don't get me wrong, theres a lot of information in this book, but if I had to pick 1 word to describe it, it would be "disorganized"

1Confusing and Overwhelming
By UG_MechEng
This is probably the worst engineering mechanics textbook out right now. My instructor assigned us this book, and I hope for the sake of future students he is not planning on using it again.

Everything is just truly overwhelming. The chapters are all really long, the second chapter is about 150 pages! All the figures and yellow boxes around equations, the extra did you know / interesting fact marginal notes littered across every page confuse and overwhelm you. You just never really get what the main idea is.

Another thing I hate about this book is they have no idea how students solve problems. It seems like every example problem is solved using computer algebra software, making it extremely difficult for the student to follow along. They use way to many extra steps in setting up problems that seemed to just confuse me.

The authors also always use non-standard units, like km/hr or mi/hr, which always require a unit conversion. And they never ever use round numbers. Angles are always like 26 degrees or 73 degrees or some arbitrary angle, Can you tell me what the sin of 26 degrees is without pulling out your calculator? In one problem the weights of the two objects were 123 lb and 234 lb. It's little things like these that are really irritating and just waste student's time. It does not help them in any way learn the principles of dynamics.

Another irritating aspect about this book is lack of a mathematical appendix. There is no appendix with some trig identities, a list of basic derivatives and a table of integrals like my other engineering books. It seems especially in this book with all the crazy angles and geometry they give you is something you would need! You would think at about 800 pages another 2 wouldn't of killed them.

One last thing, chapter ten, on three dimensional dynamics of rigid bodies, yea where is it? Please tell me? I go to the website and click on dynamics chapter 10 and all I get is Coming Soon! Gee thanks, like I dont really need to know that information!

The only thing I give them credit for is the end of the chapter summaries. This is a great idea. Unfortunately its poorly executed because they are trying to summarize their poorly written chapters / sections.

This book is just plain bad. If you are an instructor please, please don't use this text or your students will hate you!

2Impossible to follow
By student
This book is very confusing and has seemingly unconventional and difficult ways to solve simple problems. Rarely are there any relevant examples to supplement the problems. Good luck
