1. Which material is commonly used for ductwork in
commercial HVAC systems?
A. Plastic
B. Galvanized steel
C. Wood
D. Aluminum
Rationale: Galvanized steel resists corrosion and is widely used
for HVAC ductwork.
2. What does “gauge” refer to in sheet metal?
A. Heat capacity
B. Width
C. Thickness
D. Color
Rationale: Gauge numbers indicate material thickness; lower
numbers mean thicker metal.
3. In sheet metal fabrication, a brake is used to:
,A. Cut metal
B. Bend metal
C. Weld pieces
D. Measure angles
Rationale: A sheet metal brake is specifically for bending metal.
4. What is the purpose of a slip joint on ductwork?
A. Add strength
B. Allow for thermal expansion
C. Improve airflow
D. Seal joints
Rationale: Slip joints accommodate expansion and contraction
due to temperature changes.
5. When installing duct hangers, the maximum spacing for
20-gauge sheet metal is:
A. 60 inches
B. 48 inches
C. 24 inches
D. 12 inches
Rationale: Code standards limit hanger spacing based on gauge
to prevent sagging.
,6. Which tool measures the depth of a duct flange?
A. Caliper
B. Hammer
C. Micrometer
D. Screwdriver
Rationale: A micrometer provides precise thickness and depth
measurements.
7. Fitting a 90° bend using a hand seamer involves:
A. Welding
B. Crimping and bending
C. Punching holes
D. Riveting
Rationale: Hand seamers are used to form precise bends by
clamping and folding metal.
8. What type of joint uses a male and female connection to
join duct sections?
A. Weld
B. Flange
C. Drive slip joint
D. Rivet
Rationale: A drive slip joint pairs male and female parts to
connect ducts securely.
, 9. The most common fastener for sheet metal is:
A. Bolts
B. Nails
C. Screws
D. Clips
Rationale: Screws are versatile and secure in thin materials like
sheet metal.
10. What does HVAC stand for?
A. Heat Vacuum Air Circulation
B. Heating, Ventilation, and Air Conditioning
C. High Velocity Air Control
D. Hot Versus Cold
Rationale: HVAC is the standard industry abbreviation.
11. Which safety gear is required when cutting sheet metal?
A. Flip flops
B. Safety glasses
C. Loose clothing
D. Sunglasses
Rationale: Safety glasses protect eyes from metal shards and
sparks.
