Question

What is the width of feeler gauge blades (in mm) at heel and tip respectively?

(a) 12, 6

(b) 5, 11

(c) 20, 15

(d) 15, 25

This question was addressed to me at a job interview.

My question is taken from Feeler Gauges topic in division Linear Measurements of Engineering Metrology

Answer 1

The correct choice is (a) 12, 6

To elaborate: Blades are 6 mm wide at tip and width at the heel is 12 mm. Width is less at the tip because they are tapered for the outer part of their length.
