Question

caliper measurement: you are a qa inspector looking to measure a part to an accuracy of.001 inches. what tool should you use? engineering ruler depth gage micrometer dial caliper

Explanation:

• An engineering ruler typically has an accuracy of about 0.01 inches, which is not sufficient for 0.001 - inch accuracy.
• A depth gage is mainly used for measuring depths and may not offer the required precision for general part measurement to 0.001 inches.
• A micrometer is designed to measure with high precision, often down to 0.001 inches.
• A dial caliper usually has an accuracy of around 0.001 - 0.002 inches, but micrometers are more commonly associated with the 0.001 - inch accuracy requirement in such contexts (e.g., in machining and QA where very precise linear measurements are needed).

Answer:

C. Micrometer
