Fundamentals of Technology is a foundational text for engineering and technology students. The clean, clear writing style supports readers as they engage with content on the fundamentals of mechanical, electrical, and thermal systems as well as the basics of scientific measurements, data representation and analysis, and unit conversions. Specific topics covered include systematic and random error, physical quantities and their dimensions, scalars and vectors, electrical conductor design, ventilation, power trains and data description and presentation. Of special note is the final chapter, which discusses the fundamentals of engineering economics - the time value of money and comparing economic alternatives. Each well-organized chapter begins with a clear statement of learning objectives to help readers focus and an introduction to the chapter content that supports reading preparation. Fundamentals of Technology is practical, applicable, and accessible, and an excellent textbook choice for engineering programs. Chenxu Yu holds a Ph.D. in biological systems engineering with a minor in computer science from the University of Wisconsin, Madison. He is an associate professor in the Department of Agricultural and Biosystems Engineering at Iowa State University, where his research focuses on bionanotechnology and biosensor development, and their applications in biomedical diagnosis and food and water safety. Thomas Brumm earned his Ph.D. in agricultural engineering with a minor in chemical engineering at Iowa State University where he is now an engineering professor and the associate director of the Iowa State University Center for Sustainable Rural Livelihoods. Dr. Brumm researches post-harvest systems to ensure food security and how to eliminate inefficiencies in biorefineries for biomass storage.
