Question
A screw gauge has a pitch of 1.0 mm and 200 divisions on the circular scale. Do you think it is possible to increase the accuracy of the screw gauge arbitrarily by increasing the number of divisions on the circular scale?
Solution
Pitch of the screw gauge = 1.0 mm
No. of divisions on the circular scale = 200
No. of divisions on the circular scale = 200
On increasing the number of divisions on the circular scale the least count of the screw gauge will decrease. Hence, accuracy of the screw gauge increases.
