Zorluk: KolayMeasuring and Layout Tools

A technician needs to measure the small clearance gap between the electrodes of a spark plug before installation. Which measuring tool is specifically designed to measure this narrow gap?

  1. A
    Outside micrometer
  2. Feeler gaugeCevap
  3. C
    Metric box wrench
  4. D
    Hand mill file

Cevap

Feeler gauge
A feeler gauge (or thickness gauge) consists of finely calibrated, flexible steel blades of marked thicknesses designed specifically to measure narrow gaps, clearances, and tolerances such as spark plug gaps or valve lash.

Adım Adım Çözüm

1
Identify the physical requirement of the measurement task
The task requires measuring a narrow clearance between two closely spaced metal surfaces.
Spark plug gaps and valve clearances require thin, flexible, calibrated measuring elements rather than bulky measuring jaws.
2
Select the appropriate layout and measuring tool designed for gap clearance
A feeler gauge (thickness gauge) provides calibrated steel leaves that fit directly into small clearances.
Feeler gauge blades are marked in precise thousandths of an inch or hundredths of a millimeter to accurately verify gap width.
