Step 1
Identify part X
Answer
In the context of roof trusses, part X typically refers to the element that transfers loads between different members of the truss system. In roof construction, this is often a 'purlin,' which is essential for supporting the roofing material and distributing the load. Therefore, the correct identification for part X is: B - Purlin.
