A0.2280 inch
B0.2340 inch
C0.2470 inch
D0.2520 inch
AI Explanation
The correct answer is C) 0.2470 inch. To determine the correct reading of the vernier micrometer caliper scale, you need to read the main scale and the vernier scale. The main scale shows the whole number of inches, while the vernier scale indicates the decimal portion. In the illustration, the main scale shows 0.24 inch, and the vernier scale aligns with the 47th division, indicating a reading of 0.2470 inch. The other options are incorrect because they do not accurately reflect the reading shown in the illustration. Option A (0.2280 inch) and Option B (0.2340 inch) are too low, while Option D (0.2520 inch) is too high.
