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.

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.

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.
