A screw gauge of pitch 0.5 mm is to be used as a micrometre screw gauge to read correctly upto 0.001mm. What should be the number of divisions on its head scale

Answer 1

Answer:

500

Explanation:

upto 0.001mm it has to calculate correctly so least count should be 0.001mm

lc =0.001mm

pitch = 0.5 mm

lc = pitch/ no of divisions

no of divisions = pitch/ lc

= 0.5/0.001

500
