Final answer:
Inelastic materials shall not be used for fastening systems or building attachments to structures due to safety and code compliance reasons.
Step-by-step explanation:
When securing a system or building attachments to a structure, certain materials or methods are not acceptable due to safety concerns, load-bearing limitations, or building code requirements. For example, inelastic materials, such as brittle adhesives or substandard anchors, shall not be used because they may fail under stress, do not provide the necessary flexibility for structural movements, or do not adhere to the essential safety standards and guidelines. Always consult with the local building codes, engineering guidelines, and use industry-standard fastening systems designed for structural support.
