Final answer:
Plug gauges are used to fixture parts for inspection, verifying the acceptability of cylindrical parts or holes in manufacturing processes. They don't measure liquid volumes, analyze data, or conduct medical examinations.
Step-by-step explanation:
One of the uses of plug gauges is to fixture parts for inspection. Plug gauges are precision tools used to check the acceptability of diameters of cylindrical parts or holes. They are particularly used for quality control and testing during manufacturing processes. The gauge is designed to determine whether the diameter of the tested part is within the specified tolerance. It does not, however, measure liquid volumes, analyze historical data, or conduct medical examinations.
For example, a plug gauge can be used to verify the dimensions of a machined hole in a metal part to ensure it meets the necessary specifications for further assembly. Its function is strictly to check the conformity of parts, as opposed to other measurement devices like burets, which are used for measuring volumes of liquids in laboratory settings (as seen in Figure 4.16), or devices like the sphygmomanometer used to measure blood pressure in medical applications (referenced in Figures 9.6 and 11.2.5).
