Question

What is the advantage of the use of slip gauge standards for dial comparators?

(a) Size of the standard is equal to one of the limits of the plug gauge size

(b) Size of the standard is greater than one of the limits of the plug gauge size

(c) Size of the standard is less than one of the limits of the plug gauge size

(d) Slip gauges are more accurate

The question was asked by my school principal while I was bunking the class.

The doubt is from Measurements of Limit Gauges in division Testing and Calibration of Gauges and Dynamic Measurement of Engineering Metrology

Answer 1

Right option is (a) Size of the standard is equal to one of the limits of the plug gauge size

The explanation: The advantage of the slip gauge standards for dial comparators is that size of the standard is equal to one of the limits of the plug gauge size and hence the effect of errors of the comparator scale graduations is minimised.
