Final answer:
A feeler gauge is used to measure the clearance between a surface plate and a relatively narrow surface.
Explanation:
In engineering, the tool used to measure the clearance between a surface plate and a relatively narrow surface is a feeler gauge. A feeler gauge is a thin strip of metal with evenly spaced thickness markings. It is used to measure small gaps and clearances by sliding the gauge between two surfaces and determining which marking fits snugly without being too loose or tight.
For example, if you have a surface plate and a narrow surface, you can use a feeler gauge to measure the gap between them. You would select a feeler gauge with a thickness less than the gap, slide it between the surfaces, and check which marking fits properly. The corresponding marking on the feeler gauge indicates the clearance between the two surfaces.
A micrometer, caliper, and dial indicator are useful tools in engineering, but they are not specifically designed for measuring small gaps or clearances between surfaces.
