Engineering metrology is defined as the application of measurement science to engineering, which involves the measurement of geometric characteristics of objects, such as length, angle, shape, and surface finish. The scope of engineering metrology includes:

Jain’s book is famous for numericals on Sine bars (calculate angle given slip gauge stack) and Limit gauges (calculate max and min metal limits). Practice every numerical at the end of Chapters 2 and 4.
