question 84 of 100 · multiple choice
a feeler gauge can be used to?
a measure the diameter of drilled holes
b measure the degree of hardness of a tempered part
c measure the finish of a machined surfaces
d measure the clearance between parts

Explanation:

Identify the function of a feeler gauge

A feeler gauge consists of a series of thin metal blades of calibrated thicknesses used to measure gap widths or clearances between two closely spaced parts.

Evaluate the given options

• Option A: Drilled hole diameters are measured using telescoping gauges, calipers, or pin gauges.
• Option B: Hardness is measured using hardness testers (e.g., Rockwell, Brinell).
• Option C: Surface finish is measured using a profilometer or surface roughness comparators.
• Option D: Clearances between mating parts are directly measured by inserting feeler gauge blades of known thicknesses.

Answer:

• (A) measure the diameter of drilled holes
• (B) measure the degree of hardness of a tempered part
• (C) measure the finish of a machined surfaces
• (D) measure the clearance between parts (Correct answer)
