Answer:
1.20mm
Step-by-step explanation:
As shown in first figure the zero error of the
screw gauge is:
Least count of circular scale =
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
Hence, your answer is 1.20mm.
