Stress and strain are things that may significantly reduce your quality of life. We have all been at a point where we were experiencing so much stress that we just wanted to scream. This is why stress and strain formulas have been invented, so that you may rest easy again, and decrease the amount of strain that you have in your life. Stress and strain formulas like Relora Max are a outstanding way to naturally reduce the amount of stress and anxiety that exists in your life. You will no longer have to be a victim of an overly stressful life. It is not healthful for your brain to experience too much stress on a regular basis. Not only is it insalubrious for a normal brain to experience that much stress, but it may actually be dangerous. Stress in excess may often times cause severe mental disorders like depression or anxiety conditions. These conditions may cause a significant decrease in your quality of life, and you will commonly have to take medication in order to manage it at that point. Luckily, you may keep out of the way of that wholly by managing the stress before it causes those conditions. Managing stress may seem difficult, but you may do it by either decreasing the cause of stress, taking a stress formula, or using relaxation proficiencies like yoga, meditation, or even deep breathing methods. Any of these methods, or various of them used together will aid you minimize the effects that stress has on your body. Good stress and strain formulas are very necessary for your overall health. The health of your mind is crucial to your overall health, and ought to not be ignored. Excess stress may be dangerous when it starts to manifest itself in the form of a mental disorder, so do not forget to stay relaxed as much as you can. |

Every structural engineer should have a copy.
By Mr ANDREW M LESTER
A very usefull reference book for the practising structural or mechanical engineer. However it could be significantly improved by some modernisation and rationalisation ie: removing references out-dated information and references from the 1920′s and 1930′s,etc. Also by standardising variables and equations, eg: the variable for the width of a section may be ‘b’ in one chapter ‘d’ in another, also ‘tw’ may represent flange thickness rather than web thickness, etc. The book examples are all in U.S. (lbs, feet) units, annoying the European (N, m) user, and may start on one page, then be interupted by 20 pages of tables before continuing on. So the general layout could do with being significantly improved.

By DCop
I have three editions of this book: the classic 4th edition, the useless 5th edition and this, the 7th edition.
The 4th edition has simple format, is easy to use, but lacks methods for more sophisticated hand analyses and is sparse on explanations. The 5th is best used for a doorstop.
This edition is an excellent combination of the usefullness of the 4th edition with modern and more advanced methods.
The layout of each section has excellent explanatory material and provides the simple 4th edition type equations backed with more involved/advanced formulas which are very useful.
My hat is off to the authors. This is probably the best reference for those nasty stress and deflection hand calculations we all have to do from time to time.

THIS IS NOT A REVIEW ON THIS BOOK — THIS IS A COMMENT FOR MARKETPLACE SELLERS FOR THIS BOOK AND ALL ENGINEERING BOOKS — YOU NEED TO LIST WHICH EDITION YOU ARE SELLING, AS THIS IS VERY IMPORTANT FOR THE BUYERS TO KNOW! DIFFERENT EDITIONS CAN BE IN DIFFERENT UNIT SYSTEMS, AND MOST PEOPLE ONLY WANT TO HAVE A PARTICULAR EDITION (FIRST, LATEST, ETC)! — THANKS!

Rating:3 out of 5 stars
While this volume is about 30% larger than my 5th edition, it has some glaring errors. When you get pointed to a table, you will not find tables with that number. The tables are titled but not numbered according to the referring item. Major PITB trying to figure out if the table that I found was the correct one.
Excellent resource
Rating:5 out of 5 stars
Roark’s has been and remains an excellent resource for the structural engineer and designer regardless of the edition. This is a referance I use on a daily basis. Typically the first book I reach for.
Exelente libro, todo ingeniero Mecanico Debe tener Uno
Rating:3 out of 5 stars
Excelente para consegir la mayoria de las formulas relacionadas con calculos de esfuerzo y deformacion. Contiene cantidad de referencias para cada caso, de ser necesario rpofundizar mas en el tema. Lo recomiendo ampliamente, lo utilizo en todos mis calculos estructurales.

Roark’s has been not been improved
Rating:3 out of 5 stars
The book is now twice the thickness of the 6th Edition book. This makes opening and keeping open the book much more difficult. Also the paper type chosen makes it difficult to turn the pages.
I highly recommend keeping the sixth edition until they figure what is truly important to Structural/Mechanical Engineer.
Useful reference book
Rating:4 out of 5 stars
As like others, I also recommend this text for it’s overall content and subject matter. This is a helpful reference book for daily engineering applications. But – users should be aware that there are some basic mistakes in the book. The book is very user friendly to locate formulas and items. Address; the technical mistakes, and I would give if a five star rating.
Roark’s
Rating:5 out of 5 stars
I like having a Roark’s around. It is handy for stress and strain problems.
Five Stars With no Doubt.
Rating:5 out of 5 stars
During my years as Structural Calculyst this book was always on my right side on my desk, and when I needed it, it was ready to help me find my way. One really very good Engineer has never found all formulas in his head, instead he should be able of finding them out on good references and really know how to use
them all. This is the best reference book you are going to find when formulas is your subject, just buy it!
The only book I know better than this one is written in German and few people are able to read in German, so!

I should have most of this book memorized by now since I’ve relied on it for so many years. I highly recommend this text.
Great Reference Tool
Rating:4 out of 5 stars
This Book contains every fromula that i would ever need during my Mechanical Engineering Course.
It is quite easy to use, and the print is clear the index is user friendly

very useful handbook
Rating:4 out of 5 stars
Very helpful book in engineering job, but unfortunately I’ve found some mistake (the reason for 4 stars).
In general you can find lot of formulas in this book. This book is also very well known and that’s the reason for recommending it. You can just refer to Roark’s formulas and everybody knows what’s that.
still crazy after all this years…..
Rating:4 out of 5 stars
R&Y’s publication, which I became aware of in 1986 is stillan amazing collection of engineering formulas in statics, stability,dynamics and thermal calculations. The IFE uses ANSYS FEA technologyesp. for complex geometries and nonlinear issues: but once in a whilewe appreciate R&Y’s work to retain contact to quantities and forthe insight (wrt dimensioning) which interaction with formulas cangive.
R&Y’s text sections give much insight, the section onstrenght of materials terminology can be useful (learn – refresh) aswell as the brief immersion into experimental issues.
