This comprehensive updated book presents Mathcad as a means of solving engineering problems, since engineering is about finding solutions and letting other people know about them. Mathcad help finds solutions and communicate those solutions to others. Basically, there are two reasons for using Mathcad in engineering. First, it can handle the problems engineers encounter every day. Second, when an engineer has solved a problem using Mathcad, the result is a professional worksheet with the equations in readable form and results clearly displayed.With its practical and clear step-by-step procedures, this book demonstrates how to use Mathcad and shows what the Mathcad worksheet looks like through every step of the process. Each chapter opens with a lead-in describing one of the frontiers of engineering, such as global warming, biomedical engineering, optics, and risk analysis. These themes are also found throughout the book. It demonstrates how Mathcad can be used to solve real problems in various engineering disciplines, such as chemical processes, electronics, and biomedicine, as well as some that will appeal to mechanical and civil engineers.An essential Mathcad reference guide for every professional engineer.
