Summary

This text provides students with the theoretical knowledge and practical skills necessary to identify, model, and solve structural analysis problems. The material is illustrated throughout with numerous diagrammatic examples, as well as example problems similar in nature to those found in lower level strength of materials texts. The difficulty of these and the homework problems varies from simple to complex. A solutions manual is provided for lecturers who adopt the book for classroom teaching. this book mirrors the teaching method used in strength of materials courses taught in the first years of an undergraduate degree and relate this higher level treatment back to that. The author is involved in the development of the latest teaching methods (with McGraw Hill), and his style is straightforward. There is web-mounted software to back up the book's content, plus a solutions manual for instructors. There are approximately 20-30 homework problems per chapter, making a substantial body of material for teaching use.

Author Biography

George H. Staab received B.S., M.S., and Ph.D. degrees from Purdue University. After receiving his M.S., he worked as a rotor head and blade analyst for three years at Sikorsky Aircraft. After completing his doctorate, he joined the Department of Engineering Mechanics at The Ohio State University. He was the recipient of the Charles E. MacQuigg Student Award for Outstanding Teaching in 1998.
