Theory and Design for Mechanical Measurements

This work establishes and meets three goals: it provides a fundamental background in the theory of engineering measurements and measurement system performance; conveys the principles and practice for the design of measurement systems, including the role of statistics and uncertainty analysis in design; and establishes the physical principles and practical techniques used to measure those quantities most important to engineering applications such as temperature, pressure and strain. Introduces important concepts such as standards, calibration, signals and instrument response and the role of signal amplitude and frequency in instrument performance. Covers design aspects of engineering experiments as well as error sources in engineering instruments. The statistical nature of measured variables and uncertainty analysis are integrated throughout the text and contextual examples for a number of common measurement systems are provided. Numerous, practical problems enhance understanding of the material covered.
