Answer :
To solve the question of how a carpenter should lay out hip rafters with a roof pitch of 6 inches of rise per foot of run, let's break it down step-by-step:
1. Understand Roof Pitch: Roof pitch is typically expressed as the amount of vertical "rise" over a 12-inch horizontal "run". In this case, it's given as 6 inches of rise per 12 inches (1 foot) of run.
2. Use of a Framing Square: A carpenter uses a framing square to measure and mark rafters. The numbers on the square correspond to the rise and run on the rafter layout.
3. Determine Correct Layout: For a pitch of 6 inches rise for every 12 inches run, the carpenter should place the square with the rise number against the rafter board at 6 inches and the run number at 12 inches. This aligns with the given pitch ratio.
So, the carpenter should position the framing square at the measurements of 6 inches for the rise and 12 inches for the run. Therefore, the correct answer is:
B. 6 and 12.
