What does a collar tie provide in construction?

1. It increases the rigidity of trusses.

2. It provides additional strength for roof rafters.

3. It is a metal plate used to connect various components of a roof truss.

4. It stops floor joists from twisting.

5. It connects the ceiling joists to the wall plate.

6. It supports the attic floor.

The correct answer is: It provides additional strength for roof rafters.

A collar tie provides additional strength for roof rafters. In construction, collar ties are horizontal members that connect opposing rafters near the ridge of a roof. They help to prevent the rafters from spreading apart under the weight of the roof, which can lead to roof sagging or failure. By tying the rafters together, collar ties help to distribute the load more evenly, increasing the strength and stability of the roof structure. Therefore, the correct answer is B. Option A is incorrect because collar ties are not specifically designed to increase the rigidity of trusses. Option C is incorrect as it describes a different component, a metal plate used to connect various parts of a truss. Option D is incorrect because stopping floor joists from twisting is not the function of a collar tie. Option E is incorrect as it describes the function of a different component, a joist hanger, used to connect the ceiling joists to the wall plate. Option F is incorrect because a collar tie typically does not support the attic floor directly.
