MAE 1351 EXAM 1 BRAND NEW
OFFICIAL QUESTIONS WITH
ANSWERS.
1. Why are long, skinny holes difficult to produce? - correct
answer -because the drill bit has a tendency to wobble and
bend
2. Why are long, skinny protrusions difficult to produce? - correct
answer -cutting process for this protrusions causes bends
3. Blind Hole - correct answer -A hole that does not go completely
through the work piece.
4. Crest - correct answer -top surface or point joining the sides of
a thread
5. Lead - correct answer -The distance a screw thread advances
axially in one full turn
, Page | 2
6. Root - correct answer -The bottom surface or point of a screw
thread
7. Tap - correct answer -The machine tool used to form an interior
thread and is the process of making an internal thread
8. Thread note - correct answer -Information on a drawing that
clearly and completely identifies a thread
9. Thread series - correct answer -The number of threads per inch
on a standard thread
10. What types of fasteners can be used to join parts that will
permit disassembly later? - correct answer -SCREWS
11. What information is included in a standard metric thread
note? In what order? - correct answer -M axb-CD E M= symbol;
A=major diameter; B=thread pitch; C=grade tolerance;
, Page | 3
D=tolerance class; Space=thread direction; E=depth of internal
threads
12. What information is included in a standard U.S. thread note?
In what order? - correct answer -A-BC-DE A=major diameter;
B=number of threads per inch; C=series of threads; D=class of
fit; E=designates internal or external thread
13. What tools and methods are used to manufacture external
threads? - correct answer -dies or a lathe can be used to form
these
14. Describe the process and tools used to manufacture internal
threads - correct answer -a tap or a lathe can be used to cut
these
15. Describe how schematic and simplified thread
representations appear on a drawing. - correct answer -
schematic shows the threads as a series of lines that are
perpendicular to the thread axis. Simplified thread shows the
major diameter of the shaft and the threads as a dashed line
parallel to the thread axis
