Simple Tensile and Shear Structures

In this and subsequent modules, we seek to apply the concepts of materials response outlined in our discussion of Simple Tensile Response to actual structures of the sort encountered in engineering design. We will restrict ourselves initially to situations still having relatively simple geometries, specifically trusses, pressure vessels, and shafts loaded in torsion. This is done partly to introduce new concepts without excessive detail, but these structural types are far from being of academic interest only. As it is very often true that the best design is the simplest design, these simple structures make up a large part of modern construction.
