UA RIGGING FINAL EXAM NEWEST ACTUAL EXAM COMPLETE QUESTIONS AND
CORRECT DETAILED ANSWERS PLUS RATIONALES (VERIFIED ANSWERS)
Question 1
Synthetic, wire rope, and chains are most commonly used in which three sling
configurations?
A) Vertical, Horizontal, and Cross
B) Vertical, Choke, and Basket
C) Parallel, Perpendicular, and Angle
D) Single, Double, and Triple
E) Overhead, Underhand, and Side-load
Correct Answer: B) Vertical, Choke, and Basket
Rationale:, wire rope, or chains are most commonly placed in one of three sling
configurations: Vertical, Choke, or Basket.
Question 2
The Working Load Limit (WLL) for a sling is primarily dependent upon the:
A) Color of the sling
B) Brand of the manufacturer
C) Length of the sling
D) Configuration in which it is used
E) Time of day the lift occurs
Correct Answer: D) Configuration in which it is used
Rationale: The WLL changes based on how the sling is rigged. For example, a basket hitch
has a different capacity than a vertical hitch for the exact same sling.
Question 3
Which sling configuration is considered the weakest?
A) Vertical
B) Basket
C) Bridle
D) Choke
E) Inverted Basket
, 2
Correct Answer: D) Choke
Rationale: A sling placed in a Choke position is about 1/2 as strong as a sling in the vertical
position, making it the weakest of the three common configurations.
Question 4
Which sling configuration provides the greatest lifting strength?
A) Vertical
B) Choke
C) Basket
D) Single Leg
E) Knot
Correct Answer: C) Basket
Rationale: The Basket configuration is the strongest because the load is distributed
between two legs of the sling. A sling in a basket position is on average 2 times stronger
than the vertical position.
Question 5
Compared to the vertical sling position, a sling in a basket configuration is approximately:
A) Half as strong
B) Equal in strength
C) Two times stronger
D) Three times stronger
E) Four times stronger
Correct Answer: C) Two times stronger
Rationale: The source text states that a sling placed in the basket position is on average
about 2 times stronger than the vertical sling position.
Question 6
A sling placed in a choke position is approximately what percentage of the strength of a
vertical sling?
A) 25%
B) 50%
, 3
C) 75%
D) 100%
E) 125%
Correct Answer: B) 50%
Rationale: The text notes that a sling placed in a choke position is about 1/2 (or 50%) as
strong as a sling in the vertical position due to the stress at the choke point.
Question 7
Which of the following is NOT a common material used for slings in utility work?
A) Synthetic
B) Wire Rope
C) Chain
D) Hemp
E) Nylon
Correct Answer: D) Hemp
Rationale: The source material lists Synthetic, Wire rope, and Chain as the common slings.
Hemp is not listed as a modern standard for utility rigging in this context.
Question 8
Which sling configuration is most effective at minimizing slip on the load?
A) Vertical
B) Basket
C) Inverted
D) Choke
E) Bridle
Correct Answer: D) Choke
Rationale: The choke configuration tightens around the load as tension is applied, which
helps minimize slip compared to vertical or basket hitches.
Question 9
Synthetic slings are most commonly manufactured from which material?
, 4
A) Polyester
B) Polypropylene
C) Nylon
D) Cotton
E) Kevlar
Correct Answer: C) Nylon
Rationale: The text explicitly states that Nylon is the most common material used to
manufacture synthetic slings.
Question 10
What is a primary reason utility companies prefer slings?
A) They are heavy and hard to steal
B) They are strong, durable, inexpensive, and tagged with ratings
C) They are made of a single material type
D) They do not require inspections
E) They are universally conductive
Correct Answer: B) They are strong, durable, inexpensive, and tagged with ratings
Rationale: These are the specific advantages listed in the text explaining the popularity of
slings in the utility industry.
Question 11
If a synthetic sling’s name tag is missing or unreadable, what is the required action?
A) Use it only for light loads
B) Write a new tag based on estimation
C) Use it only in the vertical configuration
D) Do not use the sling
E) Ask a supervisor to sign off on it
Correct Answer: D) Do not use the sling
Rationale: Sling name tags are required. If the tag is missing or unreadable, the safety
protocols dictate that the sling must not be used.
