Multiple Choice

In common roof styles, rafters and joists correspond to which orientations?

Explanation:
Rafters are the sloped framing members that define the roof plane and give the roof its pitch, running from the ridge down to the eaves. Joists are the horizontal members that span between walls to support the ceiling (or floor above). In a common roof, you see rafters pitched (sloped) to shed water, while joists lie flat and run horizontally to create the ceiling plane. If rafters were flat, there’d be no pitched roof to shed water; if joists were pitched, the ceiling would slope instead of staying level.
