EXAM – STRUCTURAL AND
ORNAMENTAL PRACTICE QUESTIONS
AND CORRECT ANSWERS
**1. Which type of steel is commonly used for structural beams
in construction?**
A. Aluminum
B. Carbon steel
C. Copper
D. Brass
**Correct answer:** B
**Rationale:** Carbon steel is widely used for structural
applications due to its high strength and durability .
**2. On a structural drawing, what does "CL" typically stand
for?**
A. Column Line
B. Centre Line
C. Clamp Location
,2 | Page
D. Corner Level
**Correct answer:** B
**Rationale:** CL is a standard abbreviation on drawings
indicating the center line of a structural member, used for
alignment and layout .
**3. What is the primary purpose of a torque wrench?**
A. To measure length
B. To tighten bolts to a specific tension
C. To drill holes
D. To cut metal
**Correct answer:** B
**Rationale:** Torque wrenches are designed to apply a
specific torque to fasteners, ensuring connections are neither
too loose nor over-tightened .
### Section 2: Rigging and Hoisting
**4. What is the center of gravity?**
A. The lowest point of an object
, 3 | Page
B. The point at which an object's mass can be considered
concentrated
C. The strongest point of a beam
D. The location of the crane operator
**Correct answer:** B
**Rationale:** The center of gravity is the point at which an
object's mass can be considered concentrated, critical for
determining lifting points .
**5. What is sling angle effect?**
A. Sling tension changes as the sling angle changes
B. Sling color changes with angle
C. Crane capacity always increases with angle
D. Steel weight changes during lifting
**Correct answer:** A
**Rationale:** As sling angles become shallower, tension in the
sling legs increases, potentially exceeding their rated capacity.
Shallow sling angles increase the tension in each sling leg and
must be considered during rigging calculations .
**6. What is a qualified rigger expected to understand?**
