The Eighth Edition of MECHANICS OF MATERIALS continues its tradition as one of the leading texts on the market. With its hallmark clarity and accuracy, this text develops student understanding along with analytical and problem-solving skills. The main topics include analysis and design of structural members subjected to tension, compression, torsion, bending, and more. The book includes more material than can be taught in a single course giving instructors the opportunity to select the topics they wish to cover while leaving any remaining material as a valuable student reference.

As an engineer, I still have this book and still reference it from time to time.

It's a great book. It is well organized, good examples, colorful. ALL the answers are in the back. I like it.

The text by Gere and Goodno is a current version of the study of Strength of Materials, that element of Statics and Structures which considers the effects of loads on structures and ascertaining the maximum carrying capacity.

There are three main elements in understanding the subject:

1. Understanding the basic elements of statics; namely i. the sum of forces and moments equal zero, ii. stress is a force per unit area, iii. strain is a multiple of stress unless it is no longer so.

2. Applying geometry and trigonometry to static systems. This means having a good grasp of angles and distances so as best to allocate loads.

3. Paying attention to units. There is often a plethora of mixed units from lbs, N, kg, g, Pa, etc thus must be equated and often lead to either over or under stating the results.

That is it. There frankly is not much more. Like books covering this material for well over a hundred years this text does so as well. The coverage includes:

1. Stress and strain principles.

2. Applications to beams and cylinders. This is where getting the geometry correct starts to become important.

3. Bending of beams. This is the classic analysis of beams and determining maximum stress and seeing if one’s design is well within limits.

4. Columns and similar structures.

5. Indeterminate structures, the ones where there are an excess of givens.

6. Collapse and breakage.

These topics are all classic ones. The text is targeted at the undergraduate market.

I first took this material some fifty five years ago using a text by Shanley. The difference is striking. Let me list them:

1. Cost: The price then was in the single digits yet accounting for inflation the current text is 3 to 4 times more costly.

2. Pictures: Like so many texts this is filled with color pictures driving up the cost and actually distracting from the pedagogical approach. One wonders why the authors allow the publisher to embellish the text with a plethora of unrelated materials. Do the students today demand this entertainment?

3. Cohesion. The text covers the material expected but does so in my opinion in a somewhat confusing manner at times. This issue is enhanced at times by the layout of examples where the color and presentation make them unreadable and confusing.

4. Problems. In today’s environment there are many computer based approaches and tools that having hundreds of rote problems is questionable. Back in the late 50s and early 60s all we had was a slide rule. That in a sense reinforced structure. An engineer used engineering paper, paper with many small squares, to write down the problem, then draw the structure, lay out the approach to a solution and then step by step go through the process carefully checking units and calculations and finally underlining the answer for the grader. The process of doing this reinforces the concepts. Today there is a loose amalgam of back of the envelope calculations, spread sheets and even some home brewed programming. Thus perhaps the problems should be changed to reflect the design approach and not some set of PE Exam questions.

5. Focus. As one progresses through the material one jumps from a concept to an example to a set of questions. There is in my opinion a confusing jump from principles, extensions, and examples.

Overall the text does present the material, it is complete, and it can be obtained, albeit with some difficulty. I suspect that if one works through the problems one will do well on the PE exams. However there may be a disconnect from the academic and the practical.

can't say I loved the course, but this is a good text book. :) Examples are the same style as Statics and Dynamics, so that's a little extra consistency.
I'm keeping it to study for the FE later.

This book makes an already difficult course harder. I found this book frustrating. The chapters are pretty long yet don't explain much. You'll get a few formulas and an example or two only to find out they are pretty much useless to solve the end of chapter problems. The problems can be so complicated to solve that without the actual book solution you probably wouldn't even think to solve the problem that way. Newer editions of this book just change a few problems around (to make the old solution manual useless) so it's pretty much the same as previous versions.

This is still an OK book to learn the subject, but just prepare yourself to put a lot of effort and hours to get things right. I would recommend this book if you are able to work out the problems with your professor or T/A as they have the solutions and will help you understand better.

Keep in mind that I took this course as a distance student so there was no Prof to work through problems. This is a really crappy textbook. Example problems, for the most part, do not utilize the same techniques that are needed to solve end of chapter problems. Its great for the understanding of the concepts, but as far as the application side goes....it sucks something fierce. If you have to use this book for your course then do yourself a favor and buy either mechanics of materials for dummies or mechanics of materials by hibbler. They will provide you with much better examples and explanations of solutions.

I regret buying this textbook. The primary author passed away several years ago, and the quality has dropped since then. Quite frankly, I feel like this edition was released as a money grab by the publisher with no regard to quality.

As with most textbook revisions, the only changes are minor - tweaked problem sets, different example problems, etc. But many of the new solutions are just plain wrong, which caused no end of headaches for my classmates and I. Additionally, the examples are often confusing and the layout is bad. There is just no attention to detail throughout.

Please, if you a professor, please don't force your students to buy this book. And if you are a student, try to convince your professor to go with a different textbook or at least an older edition.

I used this book for a summer class and the book was everything I needed to do well in the class.
