AI Explanation
The correct answer is D) 0.4815 inch. The reading on the micrometer scale shown in figure "D" of the illustration is 0.4815 inch. This can be determined by closely examining the position of the thimble-shaped sleeve relative to the graduated scale on the micrometer barrel. The thimble has moved past the 0.48 inch mark, and the graduation line on the thimble aligns with the 0.0015 inch mark on the scale, indicating a total reading of 0.4815 inch. The other answer choices are incorrect because they do not accurately represent the measurement shown in the illustration.
