Discussion Overview

The discussion revolves around finding all the stresses on a torus pressure vessel, with participants sharing resources and debating the appropriateness of referencing literature versus providing detailed explanations. The scope includes technical reasoning and conceptual clarification related to stress analysis in engineering.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests assistance in finding stresses on a torus pressure vessel.
  • Another participant asks what the original poster has done so far in their analysis.
  • Reference is made to Roark's Formulas for Stress and Strain, suggesting it contains relevant information for the task.
  • Concerns are raised about the appropriateness of simply directing someone to a book without contributing to the discussion.
  • Some participants argue that pointing to literature can be helpful, while others believe it lacks substance in a forum setting.
  • There is a debate about the efficiency of guiding someone to a source versus providing a detailed walkthrough of the mechanics involved in the analysis.

Areas of Agreement / Disagreement

Participants express differing views on the value of referencing literature versus providing direct assistance. There is no consensus on the best approach to take in responding to the original poster's request.

Contextual Notes

Participants reference specific sections of literature and discuss the implications of their advice, indicating a reliance on established texts for complex engineering problems. The discussion reflects varying opinions on the balance between guidance and self-sufficiency in learning.

I have been goven the task of finding all the stresses on a Torus (i.e. donut) Pressure vessel. Any help would be much appreciated!
 
Engineering news on Phys.org
What have you done so far?
 
Roark's Formulas for Stress and Strain, Chapter 12, Table 28, Case 5 (at least in the 6th edition).

Careful Fred last time I referred someone here to a book I got yanked and got a warning as "not contributing to the discussion"

Personally I believe showing people what literature can be consulted is very helpful do!

I went back and checked the warning -- it was for a little different situation. Fred's reference is very specific, but your advice in the other post was to buy a Schaum's outline.

Yes because people were about to spend 100+ man hours on something that you can seriously buy for $5,-

I don't want to be a nag but the exact response was:

"Almost every single questions being asked on here, one can tell someone to go get such-and-such book. It solves nothing. Your response to someone asking a question is essentially telling that person to go get a book. That response has no substance to a discussion forum such as this. If you don't care to explain, don't respond."

So I don't see how that is different. Anyway I was kinda kidding in the first place to Fred because his advise is usually spot on.

I honestly do try to not do a reference like that when I can. I do debate with myself as to whether or not they are getting spoon fed. However, for a situation like this, the number of posts and time to walk the OP through the mechanics for this loading would be pretty extensive. That's why I just came out and told him where to look. I think there are times where pointing a person to a source is a much more efficient use of our time and bandwidth.

I agree!
