Question

Which of the following is not true for the high accuracy in the method of finding the angle of V-groove?

(a) Height of smaller should be measured by sensitive indicator

(b) Height of larger discs should be measured by using slip gauges

(c) Use of height gauge give more accuracy than slip gauges

(d) Use of both slip gauge and sensitive indicator increase accuracy

The question was posed to me during an online exam.

I need to ask this question from Measure the Angle of a V-Groove in section Miscellaneous Measurements (EM) of Engineering Metrology

Answer 1

The correct choice is (c) Use of height gauge give more accuracy than slip gauges

To explain: To increase the accuracy of the method or for higher accuracy, height of the smaller and bigger disc let h1 and h2 respectively can be measured by using sensitive indicator. Use of slip gauges for this purpose will also improve accuracy.
