2-23. Why are heat shunts used in the soldering
process?
1. To conduct heat from the
component being soldered back to
the iron
2. To increase the temperature of the
soldering iron or gun
3. To prevent damage to adjacent heat-
sensitive components
4. To decrease the temperature to the
conductor being soldered
2-24. For which of the following reasons are
conductors laced together?
1. To present a neat appearance
2. To help support each other
3. To aid in tracing conductors
4. Each of the above
2-25. Although it may be used, why is the use
of round cord discouraged for lacing
conductors?
1. It is bulkier than the flat type
2. It is more difficult to handle
3. It is not fungus resistant
4. It has a tendency to cut into wire
insulation
2-26. If you are preparing to single lace
conductors, what total length must the
lacing be in relationship to the longest
conductor?
1. One and one-half times the length
2. Twice the length
3. Two and one-half times the length
4. Five times the length
2-27. Why is a lacing shuttle used when
conductors are laced in bundles?
1. It helps prevent the conductors from
twisting together
2. It helps prevent the cord or tape
from fouling
3. It keeps the "lay" of the cord or tape
4. It ensures that hitches are evenly
spaced
2-28. Under certain circumstances, it is
permissable to twist conductors together
prior to lacing.
1. True
2. False
2-29. When coaxial cables are laced, the use of
round cord is prohibited. What additional
precaution must be observed?
1. Coaxial cables may not be laced
with other conductors
2. Bundles containing coaxial cables
must be double laced
3. Half hitches must be used in place
of marling hitches
4. Coaxial cables must not be tied so
tightly as to deform the dielectric
2-30. How should a single lace be started?
1. With a square knot and two marling
hitches
2. With a marling hitch and a
telephone hitch
3. With a telephone hitch and two half
hitches
4. With a square knot and two half
hitches
2-31. Under which of the following conditions
should a double lace be used?
1. Three coaxial cables form the
bundle
2. A maximum of six conductors form
the bundle
3. The bundle is larger than one inch in
diameter
4. The bundle exceeds 10 feet in length
2-32. How should a double lace be started?
1. With a square knot
2. With a half hitch
3. With a marling hitch
4. With a telephone hitch
