Pilkey is the New Roark for Engineers? -
Pilkey's "Formulas for Stress, Strain, and Structural Matrices"
rewrites, extends and brings up to date that much loved engineers
reference book Roark's "Formulas for Stress and Stain". An Amazon
reviewer writes "A first-class reference book, very well organized.
As a practising structural engineer, I'm commonly confronted with
strength of materials formulas for different kind of structural members
and I do extensive FE modelling. It is interesting to have analytical
formulas to check sometimes these calculations. Roark's formulas for
stress and strain had'nt satisfied me: information is not oriented for
structural engineers, introductory texts are not enough theoretical and
everywhere you have US units. In Pilkey's book, you have the
perfect structural engineer's reference: many chapters, with at first a
list of notation, explanation of conventions, and then a short
introductory course on the subject together with solved examples. After
that, there it is: magnificent well-organized "tables", with all kind
of data interesting to a structural engineer. As an example, I'll
mention that you can find plastic section modulus for about 11 type of
sections. Units are mixed for examples, but for data you have always
both US and SI units data furnished. For all entries, Pilkey's book is
far more complete than the Roark's one. You'll be surprised by the
vastness and depth of formulas furnished. Furthermore, you have
structural matrices in each case if you want to do numerical
programming. The list of references is up to date and very extensive."

Thanks to Pilkey you'll find Roark's "Formulas for Stress
and Stain"at knockdown prices. It is still an engineering class and
let's face it the laws of physics rarely change so you could snap up a
bargain from the ExcelCalcs Store via Amazon.com, Amazon.co.uk, Amazon.fr, Amazon.de, Amazon.ca
