The diagram below shows part of a micrometer screw gauge. What is the reading shown?
- A 4.01 mm
- B 4.51 mm
- C 5.00 mm
- D 4.50 mm
- E 4.60 mm
That's Correct!
It's Wrong!
The reading shown on the micrometer screw gauge is 4.51 mm. This can be determined by looking at the position of the thimble and the main scale. The thimble is aligned with the 4 on the main scale and the line on the thimble is between the 5 and 6 on the main scale, indicating an additional 0.01 mm. Therefore, the total reading is 4.51 mm.
