Okay, now I see the thimble scale clearly. The horizontal line on the sleeve aligns perfectly with the '10' mark on the thimble scale. Each division on the thimble scale represents 0.001 inch. Therefore, the reading from the thimble scale is 0.010 inches.
Now that I have both readings, I will calculate the total measurement by adding the sleeve scale reading and the thimble scale reading.
The sleeve scale reading is 0.775 inches.
The thimble scale reading is 0.010 inches.
Total measurement = 0.775 + 0.010 = 0.785 inches.
I can also verify this by looking at the provided values in the image: 0.700, 0.012, and 0.712. These seem to be examples or intermediate steps, but they don't match our calculation. Let me re-examine the sleeve scale to ensure I didn't miss anything.
Wait, let me look again at the sleeve scale. The main numbered markings are 6 and 7. In a standard micrometer, these numbers typically represent tenths of an inch, so 6 means 0.600 inches and 7 means 0.700 inches. The small lines between them are 0.025 inches each. The edge of the thimble is past the 0.700-inch mark and past three small lines (0.725, 0.750, 0.775). So, 0.775 inches is correct for the sleeve.
The thimble scale shows the line aligned with 10, which is 0.010 inches.
So, the final answer should be 0.785 inches.
I will now provide the final answer.
The solution to the problem is to read the micrometer by adding the sleeve scale reading and the thimble scale reading.
-
Sleeve Scale Reading: The edge of the thimble is past the 0.700-inch mark and past three additional 0.025-inch marks, giving a reading of 0.775 inches.
-
Thimble Scale Reading: The horizontal line on the sleeve aligns with the '10' mark on the thimble scale, which corresponds to 0.010 inches.
-
Total Measurement: 0.775 inches + 0.010 inches =
0.785 inches.
Therefore, the measurement shown on the micrometer is 0.785 inches.
