ANSWER B- shear
loads.
2- A main difference between Lockbolt/Huckbolt tension and
shear fasteners (other than their application) is in the -
ANSWER A- number of
locking collar grooves.
3- Alloy 2117 rivets are heat treated -ANSWER A- by the
manufacturer and do not require heat treatment before being
driven.
4- The general rule for finding the proper rivet diameter is
- ANSWER C- three times the thickness of the thickest
sheet.
5- The shop head of a rivet should be -ANSWER A- one
and one-half times the diameter of the rivet shank.
6- One of the main advantages of Hi-Lok type fasteners over
earlier generations is that - ANSWER C- they can be
installed with ordinary hand tools.
7- The markings on the head of a Dzus fastener identify the -
ANSWER A- body diameter, type of head, and length of the
fastener.
8- The Dzus turnlock fastener consists of a stud, grommet,
and receptacle. The stud length is measured in -
ANSWER A- hundredths
of an inch.
9- The Dzus turnlock fastener consists of a stud, grommet,
and receptacle. The stud diameter is measured in -
ANSWER C- sixteenths
of an inch.
,10- Threaded rivets (Rivnuts) are commonly used to -
ANSWER B- attach
parts or components with screws to sheet metal.
11- The installation of Cherrymax and Olympic-Lok rivets is
, accomplished by utilizing - ANSWER B- a pulling tool.
12- Hole filling fasteners (for example, MS20470 rivets) should
not be used in composite structures primarily because of the -
ANSWER
A- possibility of causing delamination.
13- Metal fasteners used with carbon/graphite composite
structures - ANSWER B- must be constructed of material such
as titanium or corrosion resistant steel.
14- Sandwich panels made of metal honeycomb construction
are used on modern aircraft because this type of construction
- ANSWER A- has a high strength to weight ratio.
15- (1) When performing a ring (coin tap) test on composite
structures, a change in sound may be due to damage or to
transition to a different internal structure.(2) The extent of
separation damage in composite structures is most accurately
measured by a ring (coin tap) test. - ANSWER B- only No. 1 is
true.
16- Which of these methods may be used to
inspectfiberglass/honeycomb structures for entrapped water?1.
Acoustic emission monitoring.2. X-ray.3. Backlighting. -ANSWER
C- 2 and 3.
17- When balsa wood is used to replace a damaged honeycomb
core, the plug should be cut so that - ANSWER C- the
grain is perpendicular to the skin.
18- When repairing puncture-type damage of a metal faced
laminated honeycomb panel, the edges of the doubler should be
tapered to - ANSWER B- 100 times the thickness of the metal.
19- One of the best ways to assure that a properly prepared
batch of matrix resin has been achieved is to - ANSWER B-
have mixed enough for a test sample.
20- How does acoustic emission testing detect defects in
composite materials? - ANSWER A- By picking up the 'noise' of
any
