english correct answers which metric must match decimals
feature correct answers the general term applied to describe a physical portion of a part or object,
such as a surface, slot, tab, pin, keyseat or hole.
tolerance correct answers total amount that a specific dimension is permitted to vary
limits correct answers largest and smallest numerical values that the feature can be.
Maximum Material Condition correct answers where a feature of a size contains the maximum
amount of material within the stated limits.
Least Material Condition correct answers where a feature of a size contains the least amount of
material within the stated limits
allowance correct answers intentional difference between the maximum material limits of mating
parts.
dimension correct answers numerical value indicated on a drawing or in documents to define the
size location or orientation of a feature.
-limit tolerance values displayed as stacked
-a zero does not precede a decimal inch that is less than one
-a specified inch dimension is expressed to the same number of decimal places as its tolerance
-fractional inches can be used, but generally indicate a larger tolerance correct answers basic
rules for displaying inch limit tolerance values correctly
Actual Mating Size correct answers The smallest distance between two parallel planes within
which the actual surface features are contained.
feature of size correct answers refers to any surface or set of parallel surfaces associated with a
size dimension.
