In a simple micrometer with screw pitch 0.5 mm and divisions on thimble 50, the reading corresponding to 5 divisions on barrel and 12 divisions on thimble is
- A. 2.620 mm
- B. 2.512 mm
- C. 5.120 mm
- D. 5.012 mm
Answer: A. 2.620 mm
Explanation: Reading = Main Scale + Thimble * LC. 5 divs on barrel = 2.5mm (assuming 0.5mm divs) or 5mm? Usually 0.5 pitch means divisions are 0.5mm. So 2.5mm. LC = 0.01. Reading = 2.5 + 12*0.01 = 2.62.
