True or False?: True
8. Does the ASME Y14.5-2018 standard apply if it is not indicated on the
draw- ing?
A. Yes, whenever ASME Y14.100-2017 is indicated, the ASME Y14.5-2018
stan- dard applies.
B. Yes, all ASME standards apply to all drawings made in North America. C. No,
ASME Y14.5-2018 requires that it be indicated on the drawing in order for it to
apply.
D. No, all applicable ASME standards must be listed on the drawing.: C. No,
ASME Y14.5-2018 requires that it be indicated on the drawing in order for it to apply.
9. An engineering drawing...
A. Defines engineering requirements for fit and function of the part
B. Communicates a general description of the part
C. Is not a legal document
D. None of the above: A. Defines engineering requirements for fit and function of the part
10. Why are engineering drawings important?
,A. They establish company policies and strategy
, B. Tolerances affect manufacturing and inspection costs
C. The number of views communicates the importance of the part
D. None of the above: B. Tolerances attect manufacturing and inspection costs.
11. What would result from not specifying the ASME Y14.5-2018 standard on
an engineering drawing?
A. The drawing becomes more of a legal document than a technical document
B. Ambiguous specifications may lead to nonfunctional parts being accepted
C. Drawing users would have to apply common sense to produce good parts
D. None of the above: B. Ambiguous specifications may lead to nonfunctional parts being accepted
12. Where does a drawing user look to identify which dimensioning and toler-
ancing standards apply to the drawing?
A. In the notes area or the title block
B. In the heading of the revision block
C. Outside the border of the drawing
D. None of the above: A. In the notes area or the title block
13. One purpose of dimensions and tolerances is to define the manufacturing
setup. True or false?: False
14. Relationships between part surfaces should be defined based on their func-
tion in the product. True or false?: True
15. The nominal size of a dimension is always the mean of the tolerance
values. True or false?: False.
16. Under ASME Y14.5, all dimensional limits are absolute. True or false?: True.
17. One use for dimensions and tolerances is to inspect the part to determine
fitness for use. True or false?: True.
18. Basic dimensions are usually specified by enclosing the dimension in
a rectangle. True or false?: True.
19. The sequence of listing notes indicates the importance of notes (1 is more
important than 4). True or false?: False.
20. Using models rather than an engineering drawing will eliminate most
sources of variation.: False.
