Step-by-step explanation:

As shown in first figure the zero error of the screw gauge is:

ZE=

50

5×0.5

=0.05mm

Least count of circular scale =

50

0.5

=0.01mm

Circular scale reading =25×0.01=0.25mm

Main scale reading =2×0.5=1mm

Actual measurement is =MSR+CSR − ZE =1+0.25−0.05=1.20mm

hope it is helping you dear
