what 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: Identify main - scale reading
The main - scale reading is 9.5 (since the 9.5 mark on the main scale is visible).
Step2: Identify thimble - scale reading
The thimble - scale has 50 divisions per revolution and each division represents 0.01 mm. The thimble - scale reading is 7. So the thimble - scale contribution is (7\times0.01 = 0.07) mm.
Step3: Calculate total reading
The total reading is the sum of the main - scale and thimble - scale readings. (9.5+0.07=9.57) mm. But we need to start with 0, so we divide by 10. The reading is (0.957) mm.
Answer:
0.957
