Description

For one- and two-semester, undergraduate-level courses in Statics and Strengths of Materials, Strength of Materials, and Engineering Mechanics in the disciplines of Engineering Technology.

Focusing on the fundamentals of material statics and strength, Applied Statics and Strength of Materials, Fifth Edition presents a non-Calculus-based, elementary, analytical, and practical approach, with rigorous, comprehensive example problems that follow the explanation of theory and very complete homework problems that allow students to practice the material. The goal of the text is to provide students with the necessary mechanics background for more advanced and specialized areas of study in the many fields of engineering technology — for example, civil, mechanical, construction, architectural, industrial, and manufacturing.
