A contractor selects heavier trusses for a house, increasing the load that the walls must support. Which change will the contractor need to make to the design?
A) increase the thickness of the wall material
B) increase the amount of insulation in the wall
C) increase the overall weight to the roof
D) increase the electrical wiring in the wall
A) increase the thickness of the wall material
The correct answer is A) increase the thickness of the wall material.
When the contractor selects heavier trusses for a house, it increases the load that the walls must support. To accommodate this increase in load, the contractor will need to make changes to the design. One of the key changes will be to increase the thickness of the wall material. This will provide the necessary structural strength to support the additional load imposed by the heavier trusses. Increasing the amount of insulation in the wall (B) will not directly address the increased load on the walls. Increasing the overall weight on the roof (C) may require additional structural support for the roof but does not directly address the load on the walls. Similarly, increasing the electrical wiring in the wall (D) is not directly related to supporting the increased load on the walls. Therefore, the correct answer is A) increase the thickness of the wall material.
