Question 166General Subjects - QMED

The correct answer is C) 0.2470 inch. The reading of the vernier micrometer caliper scale shown in figure "G" is 0.2470 inch. This can be determined by examining the main scale of the micrometer, which indicates the measurement in increments of 0.025 inch, and the vernier scale, which allows for more precise readings in increments of 0.0005 inch. In the illustration, the main scale is aligned with the 0.245 inch mark, and the vernier scale is aligned with the 0.0020 inch mark, which combined gives a reading of 0.2470 inch. The other answer choices are incorrect because they do not accurately reflect the reading shown in the illustration.
