I have two general issues with the question. Only one really relates to the site. The other one is more of an "industry" concern. Site Issues The problem with asking about general site safety is that there is always something more to think about in order to be safe. Everyone could add all of their thoughts. These could even be bullet points from ...

the immediate application to engineering is not necessarily obvious I would ask why there has to be an application. While it's true that a lot of engineering deals with taking concepts from other fields in math and science and applying them to solve real-world problems, not all engineering is about the application. Otherwise, what would be the point of a Ph....

I would like to add that although application of the Navier-Stokes equation may not be obvious, it is an equation with a lot of applications in engineering. It is a statement of the scientific principle that momentum should be conserved. In particular the NS equation shows how this conservation principle applies to a Newtonian fluid undergoing flow. The ...

Leaving aside the question of "what's going on" and how folks are interacting with each other and with each other's answers... "the theoretical edge case of a perfect cylinder or cube with perfectly flat and polished surfaces on a perfectly flat polished bottom" is off topic. I've cast the 4th vote to place the question on hold. I want to caution folks to ...

Note that both points you quote for being on topic specifically mention "engineering". Engineering is about applying the laws of physics and other sciences to real world problems. Science seeks to describe how nature works by applying observation, logical deduction, and experimental verification. Personal beliefs have no place, other than perhaps to guide ...

This sounds like a typical material selection question, and I believe this type of question is fine, as long as you aren't asking for a recommendation of a particular manufacturer or product. Personally I would love to see more of this type of question as this is related to what I do. Additionally, material selection falls under materials engineering, which ...

I think that this type of question can work. Also, the more you information (background or your own research and thoughts) that you add to the question, the better responses you usually get.
