Advanced strength and applied elasticity by Ansel C. Ugural, Saul K. Fenster

By Ansel C. Ugural, Saul K. Fenster

Engineering has its proportion of poorly-written books, and this can be one of them. instead of supply a transparent, concise reasons, the authors as a substitute concentrate on unnecessary derivations and different filler fabric that is of little use to the coed. the result's a complicated mess that makes scholars like myself pissed off and stressed.

The difficulties are just compounded by way of the inability of examples. To me, in engineering books, examples are only as very important as motives simply because let's accept it, engineering is *not* an summary artwork. Its foundation is the actual program of clinical theories to real-world difficulties. unfortunately, this book's examples are all too constrained in scope, rationalization, and intensity. The authors will derive equations for a number of sections after which have a unmarried, short, simple instance (where slightly something is defined and you are pressured to turn into a psychic to figure out their line of proposal) after which count on you to do the exponentially more challenging difficulties behind each one bankruptcy. it is ridiculous.

When I first received the publication, i assumed it was once fascinating they have been capable of cram such an concerned box right into a fairly small ebook (~500 small-sized pages). you then detect they have been in a position to do the sort of feat through skipping over large quantities of significant reasons and examples.

Be ready to be flipping in the course of the ebook regularly to refer again to formulation in quite a few chapters, and likewise be ready to scratch your head observing negative illustrations. Equations also are poorly categorized simply because if you are quick flipping during the pages, it truly is really tough to work out if an equation is one in all significance, or just an intermediate step in a derivation. reliable books field their vital or foundational equations (which after all capacity this booklet does not).

What's particularly unhappy is that poorly-written books like this one have the aptitude to show an otherwise-enthused scholar off from a subject matter. ahead of taking a category the place this booklet was once the assigned examining, i used to be fairly drawn to complex tension research. Now i glance upon the topic with disdain since it feels like a huge complicated mess.

I gave the publication one megastar for 2 purposes: first, Amazon does not let 0-star experiences, and moment, maybe the e-book will be of a few use for reference, yet so far as a textual content for studying the cloth, steer clear of in any respect expenses!
