Prep & Study Guide
1. A framed exterior wall is 20 ft long and 10 ft high. If the wall is framed with
studs at 16 in. on center, approximately how many full-height stud spaces
occur along the wall?
A. 14
B. 15
C. 16
D. 18
Answer: 15 full-height stud spaces
Rationale: Divide the 20-ft wall length by the 16-in. spacing after converting 20
ft to 240 in. The calculation is 240 ÷ 16 = 15 spaces. Actual framing layouts also
require adjustment for corners, openings, and end conditions.
, 2. When laying out a wood-framed wall, which reference dimension should
normally be established first?
A. Interior drywall dimension
B. Finished floor elevation
C. Building control lines and wall locations
D. Door casing dimension
**Answer: building control lines and wall locations
Rationale: Accurate wall layout begins from established control lines shown on
the construction documents. Interior finishes and trim dimensions depend on the
structural framing location.
3. A wall is specified as 2×6 construction using nominal lumber. What is the
approximate actual thickness of a properly surfaced stud?
A. 1 1/2 in.
B. 2 in.
C. 2 1/2 in.
D. 5 1/2 in.
Answer: 1 1/2 in. × 5 1/2 in.
Rationale: Standard surfaced nominal 2×6 lumber has an actual cross section of
approximately 1 1/2 × 5 1/2 inches.
4. What is the primary structural purpose of a header above a window or door
opening?
A. Provide insulation
B. Transfer loads around the opening
C. Support drywall only
D. Prevent air infiltration
**Answer: transfer loads around the opening
,Rationale: Removing studs creates an opening in the wall. The header transfers
loads from above the opening to the supporting studs at each side.
5. Which framing member directly supports the ends of a header at a typical
wood-framed opening?
A. Cripple stud
B. King stud and jack stud assembly
C. Sole plate
D. Rafter tie
**Answer: king stud and jack stud assembly
Rationale: The king stud extends continuously along the opening while the jack,
or trimmer, supports the header end and transfers its reaction to the foundation
or supporting structure.
6. A wall is out of plumb by 1/2 inch over a 10-ft height. What is the best
practice before sheathing?
A. Ignore the deviation
B. Plane every stud randomly
C. Correct the wall framing so it is properly plumb
D. Increase drywall thickness
**Answer: correct the wall framing so it is properly plumb
Rationale: Wall plumb is a framing quality requirement. Significant deviations
can create problems with sheathing, doors, windows, siding, cabinets, and
finishes.
7. What is the principal purpose of a sill plate anchor or foundation anchorage
system?
A. Hold insulation in place
B. Transfer lateral and uplift forces from the wall to the foundation
C. Support ceiling drywall
D. Establish roof pitch
, **Answer: transfer structural forces from the wall to the foundation
Rationale: Anchors connect the framed wall assembly to the foundation and
resist forces such as shear, uplift, and overturning.
8. Which condition most seriously reduces the structural capacity of a load-
bearing stud?
A. Minor surface discoloration
B. A properly placed small nail hole
C. Excessive notching or drilling beyond permitted limits
D. Factory-applied grade stamp
**Answer: excessive notching or drilling beyond permitted limits
Rationale: Removing excessive wood from a stud reduces its cross-sectional area
and can significantly weaken the member, particularly under axial and bending
loads.
9. What is the primary purpose of wall sheathing in a conventionally framed
structure?
A. Only provide thermal insulation
B. Provide structural resistance and a substrate for exterior finishes
C. Replace all wall studs
D. Prevent every form of moisture intrusion
**Answer: provide structural resistance and a substrate for exterior finishes
Rationale: Structural sheathing can contribute to wall shear resistance and
provides a surface for weather-resistant assemblies and cladding. It is not, by
itself, a complete moisture-control system.
10.In a wood shear wall, why is the nailing schedule especially important?
A. Nails determine paint adhesion
B. Nail spacing affects the transfer of shear forces into the sheathing
