Theory and Design for Mechanical Measurements provides a well-founded, fundamental background in the theory and practice of engineering measurements. Designed to align with a variety of undergraduate course structures, the book offers a rigorous treatment of the subject with a flexible pedagogical framework for use in graduate studies, independent study, or professional reference. It integrates the necessary elements to conduct engineering measurements through the design of measurement systems and measurement test plans, with an emphasis on the role of statistics and uncertainty analyses in that process. This International Adaptation offers new or expanded material on several topics, mostly under Fundamentals of Measurement, Systematic and Random Errors and Standard Uncertainties, Sensors and Actuators. Along with extensive coverage of device selection, test procedures, measurement system performance, the book includes practical discussion on real-world methods and techniques. The current applications of measurement theory and design are presented with examples, case studies, and vignettes. The updated end-of-chapter material includes significant number of new problems.�
