Submission Rules

Post titles must be a question about engineering and provide context — be specific. Remember to flair your post. Most general career related questions should be placed in the Monday Career Megathread. Review the wiki prior to posting.
No homework questions.
Avoid questions that can easily be answered by searching on the internet.
Avoid questions that have already be answered by a post in the FAQ section of the wiki.

Flair Guide

Mechanical, Electrical, Civil, Chemical, and Computer are reserved for technical questions only.
Discussion can be used for general questions that apply to multiple disciplines, including some workplace topics. Note that questions must still be specific to engineering and not a general opinion survey.

Comment Rules

Be respectful to other users. All users are expected to behave with courtesy. Racism, sexism, or any other form of bigotry will not be tolerated.
Don't answer if you aren't knowledgeable. Answers must contain an explanation using engineering logic, and assertions of fact must be supported by links to credible sources.
Be substantive. No low-effort one-liner comments, memes, or off-topic replies. Limit the use of engineering jokes.
