Question

Which of the following is used to measure the distance across the pins when included angle of the dovetail is determining by using pins?

(a) Vernier

(b) Micrometer

(c) Screw gauge

(d) Slip gauge

This question was addressed to me in an internship interview.

I need to ask this question from Determine the Included Angle of an Internal Dovetail topic in division Miscellaneous Measurements (EM) of Engineering Metrology

Answer 1

The correct answer is (b) Micrometer

For explanation I would say: Micrometer is used to determine the distance across the pins. For setting pins at required height slip gauges are used.

Dovetail joints can be used in jet engines for attaching turbine blades to the shaft in jet engines and also for clockmaking, joining adjacent sections etc.
