Question

Observations
1. Determination of Least Count of the Screw Gauge
1 Linear Scale Division, LSD = 1 mm
Number of full rotations given to screw =4
Distance moved by the screw = 4mm
4 mm
Hence, pitch pr
4
= 1mm
Number of divisions on circular scale=100
Hence, least count, LC
Imm
100 = 0.01 mm=0.001 cm
2. Zero Error
(i) zero error =-------mm
(ii) zero error=-------mm
(iii) zero error =--------mm
Mean zero error, e= --------mm​
