Which of the following is NOT a measuring device used during reuse inspection?

1. Micrometer
2. Feeler gauge
3. Steel ruler
4. Dial indicator

Answer :

To determine which of the listed items is NOT a measuring device used during a reuse inspection, we need to understand the function of each tool:

  1. Micrometer: A micrometer is a precision instrument used for measuring small distances with high accuracy, typically in mechanical engineering and metalworking.

  2. Feeler Gauge: This is a tool used to measure gap widths or clearances between two parts. It's commonly used in automotive and engineering applications to ensure proper spacing.

  3. Steel Ruler: A steel ruler is a flat measuring instrument used for drawing straight lines and measuring lengths in two-dimensional spaces. It serves basic measuring functions in various fields.

  4. Dial Indicator: This tool measures small distances or angles, often used to check the variation or movement in mechanical parts.

In the context of a reuse inspection, which usually involves examining and verifying the dimensions and conditions of components for their reusability, all of the tools except the Steel Ruler may be directly involved in measuring specific tolerances and clearances. A Steel Ruler is more of a general-purpose measuring device and may not provide the precision required in many engineering inspection processes.

Therefore, the correct answer is Steel Ruler.
