Can wood trusses be cut or notched if approved by a design professional?

1. Yes

2. No

3. Only in emergencies

4. Only if they are unused

The correct answer is: Yes

Wood trusses can indeed be cut or notched if such modifications are approved by a design professional. This is because trusses are engineered components that are designed to support certain loads and stresses. Any alterations, such as cutting or notching, can potentially compromise their structural integrity. Therefore, it is crucial that modifications are guided by the assessment and approval of a qualified design professional who can ensure that the changes will not negatively impact the performance or safety of the trusses. Modifications approved by a design professional typically come with a set of conditions or adjusted specifications that help maintain the structural integrity. This explains why it is permissible, as proper oversight ensures that any risks associated with alterations are mitigated. The other options imply restrictions that do not consider the importance of professional oversight or the engineering context. In emergencies, for example, there might be an immediate need to alter components, but this should still be reviewed afterward by a design professional to guarantee safety. Additionally, asserting that alterations can only occur if the trusses are unused disregards scenarios where modifications might be necessary for ongoing projects while ensuring safety measures are adhered to. Thus, having a professional's approval stands as the essential factor for the viability of such actions.
