8. Which of the following option is correct for given statements?
Statement 1: Slip gauge and its accessories can be used as a limit gauge.
Statement 2: Slip gauge and accessories can be used for the measurement of plug gauge but not for ring gauges.
a) T, F
b) F, F
c) T, T
d) F, T
View Answer

Answer: a
