Define engineering failure. Give two examples of the following: a) Designing to avoid failure and b) Designing to achieve failure.

Solution

An engineered system fails when it stops working. (Usually this means it broke, or broke down, or shut down.) A \"failure\" should not be mistaken for a \"malfunction,\" in which case the system may work properly next time you turn it on. (In the case of structures, however, it\'s pretty difficult to mistake the two.) As far as malfunctions are concerned, though, one should also recognize that \"malfunction\" + \"loss of opportunity\" = \"failure\" even if the system does work properly next time it\'s used.

1) Designing to avoid failure is used in situation where there is a chance of loss of public life such as building houses, bridges, cars etc.

2) Designing to achive failure is used in experimental/laboratory conditions majorly to determine the tensile strength of specimen of known or unknown materials.
