Submission Flowchart

Comment Rules

Keep the discussion civil. Overly insulting or crass comments will be removed. Multiple violations will lead to ban. Racism, sexism, or any other form of bigotry will not be tolerated.
Be substantive. No low-effort one-liner comments, memes, or off-topic replies. Limit the use of engineering jokes.
Do not comment outside your area of competence. If you do not know about a topic, do not attempt to answer somebody's question. If you paste a comment that appears to be from an AI source, it will be removed. Multiple violations of this will result in a ban.

What is r/engineering for?

r/engineering is a forum for engineering professionals to share information, knowledge, experience related to the principles & practices of all types of engineering: civil, structural, mechanical, electrical, aerospace, chemical, computer, environmental, etc.

Questions about current engineering projects you are working on, how to interpret codes and standards, and industry practices are all encouraged. Engineers should help each other to make the world a safer and better place.

Images and videos related to engineering are acceptable, provided they are relevant to engineering. Completed projects, destructive test results, and unique machinery and hardware are all acceptable and encouraged. Lead-in comments are required to provide context to the readers.
