The reading on the micrometer scale shown in figure "D" in the illustration is __________. Illustration GS-0081

Correct Answer: Option D — 0.4815 inch

The micrometer reading is determined by summing the sleeve reading (0.475) and the thimble reading (0.0065). In this specific illustration, the thimble aligns with the 0.0065 mark beyond the 0.475 graduation, resulting in a total measurement of 0.4815 inches, accounting for the vernier scale precision.
