Explanation:

Step1: Identify main - scale reading

The main - scale reading of a 0 - 1" micrometer is the value on the fixed sleeve. Here, the main - scale reading is 0.0000 inches (since the zero on the thimble has not passed the 0.025" mark on the main scale).

Step2: Identify thimble reading

Each division on the thimble of a 0 - 1" micrometer represents 0.0001 inches. The thimble reading is 0.0165 inches (as the 16.5th division on the thimble is aligned with the reference line on the main scale).

Step3: Calculate total reading

The total reading of the micrometer is the sum of the main - scale reading and the thimble reading. So, the total reading is \(0.0000+ 0.0165=0.0165\) inches.

Answer:

0.0165
