reading micrometers practice #2 (fr)\nwhat is the decimal reading of this micrometer? (make sure your answer starts with 0, contains a decimal., and is accurate to 3 digits.)

Answer

Explanation:

Step1: Determine main - scale reading

The main - scale reading is 5 mm.

Step2: Determine thimble - scale reading

The thimble - scale has 20 divisions per mm. Each division is 0.005 mm. The thimble - scale reading is 17 × 0.005 = 0.085 mm.

Step3: Calculate total reading

The total reading is the sum of the main - scale and thimble - scale readings. 5 + 0.085 = 5.085 mm. But we need to start with 0, so we divide by 10: 0.5085 ≈ 0.509.

Answer:

0.509
