Summary

For one/two-semester, undergraduate-level courses in Statics and Strength of Materials, Engineering Mechanics, and Strength of Materials. Focusing on mastery of the basics, this book presents a non-Calculus based elementary, analytical, and practical approach to the principles and physical concepts of Statics and Strength of Materials. It features a rigorous, comprehensive step-by-step problem solving approach; an abundance of worked-out example problems and homework problems; and a focus on principles and applications applicable to many fields of engineering technology e.g., civil, mechanical, construction, architectural, industrial, and manufacturing.
