What is the component that directly supports roof sheathing?

ceiling joist
lateral chord
purlin
rafter
roof truss
tie beam

The correct answer is: rafter

The correct answer is D. rafter. Rafters are the inclined structural members that directly support the roof sheathing. They are typically spaced evenly across the width of the roof and provide the primary framework for the roof structure. Ceiling joists (option A) are horizontal framing members that support the ceiling below and are not directly related to supporting roof sheathing. Lateral chords (option B) are part of a truss, not the component that directly supports roof sheathing. Purlins (option C) are horizontal members applied to the top of the trusses for additional support but do not directly support the roof sheathing. Roof trusses (option E) are pre-engineered roof structures composed of triangles for support and are not the specific component directly supporting roof sheathing. Lastly, tie beam (option F) is a horizontal beam that ties the feet of opposing rafters together and is not directly related to supporting roof sheathing.
