Methods and techniques of measurements are becoming increasingly important in engineering in recent years laboratory programmes have been modernized, sophisticated electronic instrumentation has been incorporated into the programme and newer techniques have been developed. This book dwells on the physical aspects of measurement techniques.

For the measurement to be meaningful, the nature and magnitude of error should be known. The book, thus begins with error analysis and applications of statistical principles to attain a measurement value as near the true value as possible. The methods of measuring mechanical quantities are discussed subsequently, overing both the basic and derived quantities. Effort has been made to present the subject in S.I. units. Some of the recent developments such as laser-doppler techniques, holography, have also been included. The coverage is such that the book will be useful both of graduate and post-graduate students and will also serve as a constant reference for researchers.
