b. Door casing
c. Roof framing system
d. Baseboard trim
Rationale: The roof framing system, including rafters or trusses,

walls and other supporting members. Interior finishes and trim do not
serve as primary structural load paths.
2. What is the primary purpose of a sill plate in wood framing?
,a. To support ceiling finishes
b. To connect the wall framing to the foundation
c. To provide roof ventilation
d. To finish the exterior wall surface
Rationale: The sill plate is installed on the foundation and provides the
connection between the foundation and the wood-framed wall. It also
helps distribute wall loads and provides a base for the studs.
3. Which framing member is installed vertically between the bottom
and top plates of a typical wood-framed wall?
a. Joist
b. Rafter

d. Stud
Rationale: Wall studs are vertical framing members that transfer
loads from the top plate toward the bottom plate and foundation.
Joists are generally horizontal floor members, while rafters are roof
members.

Rationale: Jack studs, also called trimmer studs, support the ends of

opening?
, a. Support roof shingles
b. Provide full-height framing alongside the opening

b. Collar tie
c. Bottom plate
d. Rafter tie
Rationale: The bottom plate connects the wall studs at their lower
ends and provides a surface for fastening the wall to the foundation

framing?
a. Support floor finishes
