Wired Faculty App

What is the least count of a screw gauge, whose circular scale is divided into 100 equal parts and the pitch of the screw is 1 mm?

Solution

Number of divisions on circular scale, N = 100
Pitch of screw gauge is, d = 1 mm

space space therefore

Least count =

straight d over straight N

equals fraction numerator 1 mm over denominator 100 end fraction equals 0.01 space mm

equals space fraction numerator 1 space mm over denominator 100 end fraction equals 0.01 mm
