- Civil Engineering
- Software Engineering
- Computer Engineering
- Bio-Medical Engineering
- Quality Engineering
- Cost Engineering

and many more. Depending on the community, web traffic, there some engineering questions are better suited on another forum. In such cases we should encourage and guide the poster to such more appropriate forums.
We are not experts in every topic, thus we should encourage poster to find the answer as oppose to crucifying the user.
I point to a comment by @GlenH7 : be nice to the poster
