A dial gauge is a

• instrument

• limit gauge

• comparator

• inspection fixture

Why a revolution counter is used in dial gauge?

• To withstand sudden shock

• To indicate correctly the number of revolution

• To count and display the number of revolutions

• To transfer motion at right angle

The ASME standard of geometrical dimensioning and tolerances (GD&T)

• Y14.3

• Y14.5

• Y14.6

• Y14.8

Name the GD&T symbol

• Feature Control Frame

• Datum Feature

• Basic Dimension

• Limit of Size

Interpret the feature control frame

• The perpendicularity of the feature must be within a 0.2 diametrical tolerance zone relative to Datum A and B

• The perpendicularity of the feature must be within a 0.2 tolerance zone relative to Datum A and B at maximum material condition

• The perpendicularity of the feature must be within a 0.2 diametrical tolerance zone relative to Datum AB

• The perpendicularity of the feature must be within a 0.2 tolerance zone

The definition of allowance

• The condition where a size feature contains the maximum amount of material within the stated limits of size

• Difference between the least material condition of two mating parts

• Nominal dimension from which tolerances are derived

• Difference between the maximum material condition of two mating parts
