Question

What is the primary reason there are limits on deflection?

A. To ensure human comfort.
B. To avoid under-design by engineers.
C. To prevent water ponding.
D. To mitigate the risk of catastrophic failure.

Answer 1

The primary reason there are limits on deflection in engineering is to mitigate the risk of catastrophic failure. Limits on deflection help ensure the safety and functionality of structures. They prevent excessive displacement or bending that could lead to structural instability and malfunction.

Step-by-step explanation:

The primary reason there are limits on deflection in engineering is to mitigate the risk of catastrophic failure. Deflection refers to the displacement or bending of a structure or component under external loading. If a structure deflects too much, it could lead to structural instability, collapse, or malfunction.

For example, in buildings, excessive deflection could result in discomfort for occupants (human comfort) and potential damage to the structure. In dams, excessive deflection could lead to water ponding and structural failure.

By setting limits on deflection, engineers ensure that structures remain safe, functional, and within acceptable limits of performance.
