Answer
Explanation:
Step1: Read main - scale value
The main - scale reading is 5.5 mm (the value on the main scale to the left of the thimble).
Step2: Read thimble - scale value
The thimble scale has 0.000 mm (the mark on the thimble that lines up with the horizontal line on the main scale).
Step3: Calculate total reading
The total reading is the sum of the main - scale and thimble - scale readings. So, (5.5+0.000 = 5.500) mm.
Answer:
5.500
