What is the reading of the vernier micrometer caliper scale shown in figure "G" in the illustration? Illustration GS-0083

Correct Answer: Option C — 0.2470 inch

Vernier micrometer readings are determined by adding the main scale, the thimble scale, and the vernier scale value. In this specific configuration, the alignment of the vernier graduation with the thimble graduation provides the final digit, resulting in a precise measurement of 0.2470 inches for the specified mechanical component.
