The following statements pertain to the roof truss.
1. In the case of a queen-post truss, the tie beam will be under tension while the straining beam and struts are under compression.
2. Due to the triangular structure of the King-post truss, the members are either under tension or compression.
Validate the statements as correct/incorrect and choose the correct answer.

Answer: C
Both statements are correct. In a queen-post truss the tie beam at the bottom is in tension, since it holds the feet of the principal rafters together, while the straining beam, which joins the tops of the queen posts, and the struts carry compression. In a king-post truss, which is a simple triangulated frame, each member is either in tension (the tie beam and the king post) or in compression (the principal rafters and the struts), and no member is under bending when the loads act at the joints.
