SECTION A: Wood Framing & Structural Components (Q1–6)
Q1: A wall framing member that runs vertically from the sill plate to the top plate is called a:
A. Rafter
B. Stud [CORRECT]
C. Joist
D. Header
Correct Answer: B
Rationale: A stud is the vertical framing member in a wall that supports the top plate and transfers loads
downward.
Q2: In platform framing (the most common residential method), each floor acts as a platform for the

A. Requires less lumber overall
B. Fire stops are built into the design at each floor level [CORRECT]
C. Allows for taller wall heights without interruption
D. Uses continuous studs from foundation to roof
Correct Answer: B
Rationale: Platform framing naturally creates fire stops at each floor because the platform separates the
stud cavities, improving fire safety per IRC requirements.
Q3 (Calculation): How many board feet are in a 2" × 6" × 10' framing member?
A. 5 board feet
, B. 10 board feet [CORRECT]
C. 12 board feet
D. 20 board feet
Correct Answer: B
Rationale: Board feet = (thickness in inches × width in inches × length in feet) ÷ 12; (2 × 6 × 10) ÷ 12 =
120 ÷ 12 = 10 board feet.
Q4: Which of the following is the correct minimum end-bearing length for a wood floor joist on a wood
sill plate per IRC standards?
A. 1 inch
B. 1.5 inches [CORRECT]
C. 3 inches
D. 4 inches
Correct Answer: B
Rationale: The IRC requires a minimum of 1.5 inches of end bearing for floor joists on wood supports to
ensure adequate load transfer and stability.
Q5 (Identification): A horizontal framing member placed over a window or door opening to support the
load above is called a:
A. King stud
B. Jack stud
C. Header [CORRECT]
D. Cripple stud
Correct Answer: C
Rationale: A header is the horizontal beam installed above openings in walls to carry the structural load
from above down to the adjacent studs.
