A screw gauge has a pitch of 1 mm and 200 divisions on the circular scale. Is it possible to increase the accuracy by increasing the number of divisions on the circular scale? |

Answer» Yes because the least accurate measurement, i.e., least count of a screw gauge. = \(\frac{Pitch}{number\, of\, division\, on\, circular\, scale}\) ∴ Least count is inversely proportional to number of division on the circular scale. So, with the increase in number of division on the circular scale, the least count will improve. In simple words, accuracy of screw gauge will increase. |
