Framing & StructuralCâu 329 / 700
CALCULATION: A hip rafter runs diagonally across the plan corner of a roof. Compared with a common rafter having the same rise, the hip rafter is:
a.Longer, because its horizontal run is the diagonal of the common rafter's run
b.Shorter, because it is steeper
c.Exactly the same length
d.Always half the length of the common rafter
Giải thích
A hip rafter travels along the diagonal of the corner, so its horizontal run is longer (the diagonal of the square formed by the common-rafter runs), making the hip rafter longer than a common rafter of the same rise. It is not shorter, equal, or half length; the diagonal run is what lengthens it.
