5. GD&T Concepts questions well
answered already passed
What is a basic dimension? - ANS ✔A numerical value used to describe the theoretically exact
size, true profile, orientation, or location of a part feature or datum target.
How is a basic dimension denoted? - ANS ✔By placing a rectangle around a dimension.
When basic dimensions are used to describe part features, they must be accompanied by what?
- ANS ✔A geometric tolerance.
A good way to look at basic dimensions is that a basic dimension only specifies___________ the
requirement. To complete the requirement, a____________________ must be applied to the
feature. - ANS ✔Half/geometric tolerance
What are the two applications for basic dimensions? - ANS ✔1. To describe theoretically exact
size, location, or orientation of a part feature.
2. To describe datum targets.
What are datum targets? - ANS ✔Symbols that describe the size, shape, and location of gage
elements used to establish a datum plane or axis.
What is a gage element? - ANS ✔The physical portion of a gage.
Is there a geometric tolerance associated with the basic dimensions used to define datum
targets? When basic dimensions define datum targets, what applies? - ANS ✔No/gagemakers'
tolerance
