It is expected that students using this text will have completed a course in statics. However,
Chap. 1 is designed to provide them with an opportunity to review the concepts learned in that

The properties of moments and centroids of areas are described in Appendix A; this material
can be used to reinforce the discussion of the determination of normal and shearing stresses
