Question

Which of the following gauge is generally used to measure distance between top of ball and tapered hole in the method of checking angle of a tapered hole?

(a) Depth gauge

(b) Slip gauge

(c) Height gauge

(d) Angle gauge

This question was addressed to me by my college professor while I was bunking the class.

This interesting question is from Check the Angle of a Tapered Hole in section Miscellaneous Measurements (EM) of Engineering Metrology

Answer 1

Right option is (c) Height gauge

To elaborate: In this method of checking the angle of tapered hole the bigger ball of radius let R is placed in the hole and distance H. The distance between tapered hole and the top of the ball is measured with height gauge.
