All problems in the final section of each chapter require the use of the Knovel website (http:// www.knovel.com/web/portal/browse). These three problems are designed to provide an introduction to Knovel, its website, and the interactive tools available on it. For a detailed introduction describing the use of Knovel, please visit your textbook’s website at: http://www.cengage.com/engineering/askeland and go to the Student Companion site.
