Description

text for tile various loadirlg conditiorls encountered. Thus, students are preser~tedat an early stage with a method of solution that combines the analysis of deformations with the conventional analysisic of forces used in statics, and will have become thorougllly fan~iliarwith it by the end of the course. The concept nf plastic deformation is also introduced in Chap. 2, where it is applied to the analysis of members under axial loading, while problems involving the plastic deformation o f circular shaRs and of prismatic beams are considered in optional sections of Chaps. 3 and 4, respectively. On the other hand, while the concept of stress at a point is introduced in Chap. 1 , the discussion of the Wdnsfomation of stresses is delayed until Chap. 7 , afier sl~rdenlshave discovered Lor thctnsclves the need fur special techniques, such as Mohr's circlc. In this cdition, shear and be~~ding-momer~t diagrams are introduced

at the beginning of Chap. 5 and applied irnmediatcly to tbc design of bcatns in that cl1aptc.r and in thc ncxt. A bricf description, chapter by chapter, of the topics includcd in the text will be found in the following pagcs. It is hopcd that this material will help instructors organize their courses to best fit the needs of heir students.

The authors of ~WechnnicsufdUulerids, 4 h , wish to thank Professor Ucan P. Updike of the Department o f Mechanical Engineering and Mechanics at Lehigh University for having written the problem solutions contained in this

Manual.
