Question

Which of the following can be used in the case of threads to measure the difference in heights of discs when the angle of V-groove?

(a) Slip gauges

(b) Height gauges

(c) Screw gauges

(d) Dial indicator

I have been asked this question in an internship interview.

This key question is from Measure the Angle of a V-Groove topic in portion Miscellaneous Measurements (EM) of Engineering Metrology

Answer 1

Right choice is (d) Dial indicator

The best I can explain: This method is also very suitable for measuring the angle of shallow grooves and threads.

To measure the difference of disc height say, (h2-h1) in case of threads, can be measured by dial indicator.
