I am attempting to learn more about the field of statics, engineering concepts related to stability under tensile and compressive stress, and related topics. I realize this a broad area of physics but educating myself piece by piece on wikipedia is tedious and disjointed, and Khan academy doesn't have any lessons on these subjects. I've read quite a bit about stress v.s. strain and elastic v.s. plastic deformation but I'm looking for resources on the finer points such as what makes one shape more stable than another or the various types of stress which might act on a building or an aircraft, that sort of thing. Could anyone recommend a good place to start; web pages or books?
