Question

According to BIS, What is the thickness of feeler gauge blades for set number 1?

(a) 0.3 to 0.1

(b) 0.03 to 0.1

(c) 0.05 to 0.3

(d) 0.5 to 0.3

This question was addressed to me in a job interview.

My question is based upon Feeler Gauges in chapter Linear Measurements of Engineering Metrology

Answer 1

Right answer is (b) 0.03 to 0.1

For explanation I would say: Set number 1 has 8 blades in the set with a thickness of blades from 0.03 to 0.1 in steps of 0.01.
