1. Which framing member primarily transfers roof loads from the
rafters or trusses to the exterior wall framing in a conventional
wood-framed building?
A. Sill plate
B. Top plate
C. Sole plate
D. Jack stud
The top plate receives loads from rafters, trusses, and upper wall
framing and distributes those loads to the studs below.
2. In conventional wood platform framing, what is the primary
purpose of the sill plate?
A. To support roof sheathing
B. To provide lateral support to rafters
C. To connect the wall framing to the foundation and distribute loads
D. To replace the need for anchor bolts
,The sill plate transfers wall loads to the foundation and provides the
connection between the wood framing and the supporting foundation.
3. A carpenter is installing a load-bearing header over a window
opening. What is the primary purpose of the header?
A. Prevent condensation around the window
B. Transfer loads around the opening to the supporting studs
C. Provide a nailing surface for drywall only
D. Eliminate the need for king studs
A header spans the opening and transfers loads from the framing above
to the jack or trimmer studs at the sides of the opening.
4. Which framing component directly supports one end of a header
and transfers its load vertically toward the foundation?
A. Cripple stud
B. King stud
C. Jack stud
D. Rafter tie
The jack stud, also called a trimmer stud, supports the end of the header
and transfers its concentrated load downward.
5. When installing dimensional lumber floor joists, which condition
generally requires particular attention because excessive notching
can weaken the member?
A. Notching at the center of the top edge only
B. Notching near the middle of the span
,C. Painting the joist ends
D. Installing joists perpendicular to beams
Notches remove structural material and can significantly reduce bending
capacity, particularly when placed in critical portions of the joist.
6. What is the principal structural purpose of subfloor sheathing
installed over floor joists?
A. Prevent all thermal expansion
B. Provide a structural diaphragm and support the finished floor
C. Replace foundation anchorage
D. Eliminate the need for joist hangers
Properly fastened subfloor sheathing provides a structural walking
surface and contributes to the floor diaphragm that transfers lateral
forces.
7. Which type of lumber is generally most appropriate for structural
framing when a specific grade and species have been specified by
the plans?
A. Any kiln-dried lumber regardless of grade
B. Utility-grade lumber
C. The specified species and structural grade
D. Ungraded reclaimed lumber
Structural framing members must meet the specified species, grade,
size, and applicable design requirements because strength properties
vary substantially among lumber grades.
, 8. What is the primary reason for installing a continuous load path in a
wood-framed building?
A. To improve paint adhesion
B. To reduce interior humidity
C. To transfer structural loads continuously from upper components to
the foundation
D. To eliminate the need for bracing
A continuous load path allows gravity and lateral forces to be
transferred through connected structural components into the
foundation and supporting ground.
9. A carpenter is installing wall studs at 16 inches on center. What does
this measurement mean?
A. The clear distance between studs is exactly 16 inches
B. The outside edges of studs are exactly 16 inches apart
C. The centers of adjacent studs are 16 inches apart
D. The studs are 16 inches wide
On-center spacing measures the distance from the centerline of one
framing member to the centerline of the adjacent member.
10. Which tool is most appropriate for checking whether a wall is
vertically aligned?
A. Chalk line
B. Combination square
