This new book offers an original approach to second-level course in Mechanics of Materials/Strength, taken by Mechanical, Aerospace, and Civil Engineering students in their junior/senior year. Barber begins by discussing the tenets of engineering design, and links subsequent mechanics concepts to the design work practicing engineers do. Physical and often intuitive interpretations are provided, in addition to analytical explanations. The author also presents simple experiments students can perform to gain a better understanding of mechanics concepts. Throughout the book he strives to simplify the mathematics and engineering terminology, and develop explanations in a way students can follow clearly.
