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

The vernier micrometer scale reading is calculated by adding the main sleeve graduation (0.240) to the thimble graduation (0.007). The alignment of the vernier scale mark with the thimble graduation confirms the final digit, resulting in a total measurement of 0.2470 inches, which is standard for high-precision mechanical measurements.
