this is another example of your misuse of technical jargon in an effort to impress (confuse) the lesser educated masses (us). I cannot envision that a catenoid has any relationship to an iron engine block attached to an engine stand . . . . . . .
Each incremental element in the x-axis of a cantilevered beam (engine block) is subject to the acceleration due to gravity and because the material is contiguous it transmits an ever increasing torque to the initial element. The torque places each succeeding element in a decreasing ratio of tension to compression till finally they balance at the unsupported end of the beam.

An anchored contiguous suspension cable under the acceleration due to gravity transmits an ever increasing tension vector to the initial element as the cable increases in length but a decreasing value of tension for every succeeding element till finally the tension vector balances with the opposing elements leading to the second anchor.

The inverse of the catenoidal curve of the cable will be related to that of the cantilevered beam as the uniform force on both and each contiguous linear element of both is the acceleration due to gravity due to their own self-load.

I spent a lot of time doing interdisciplinary studies. A major impediment to progress in solving equivalent and/or related problems and the progress in knowledge is the use of jargon so as to exclude those who are not of the cognoscenti, tribe or professional society. I will gladly mix registers to combat this and thereby encourage people TO LOOK UP WORDS AND IDEAS THEY DO NOT RECOGNIZE.

I think it is better to assume ignorance over stupidity. As Judge Judith Sheindlin says, “You can't fix stupid.” I think most people want to learn or they would not populate this forum.

Part of learning someone, one will need the ability to talk at their level about said subject as the student is already less informed than the presenter.

While I have no doubt your experienced and intelligent you dont make the most intelligent choices when commenting.

Thank you for your post however as I value everyone's facts and opinions to a topic I am interested in.

I had the opportunity to become a teacher and I chose not to because I did not want to inadvertently damage young minds.

The learning materials to study most subjects are readily available and free.

The onus is on the student to make the effort.

I appreciate Kevin's writing style and vocabulary; it's good exercise to have to stretch your mind a bit when delving beneath the surface of sometimes simple-appearing topics. :)

Actually I scan the ground and try to anticipate tripping over things or people running into me and causing me to fall. That was because I was extremely foolish and ignored my own behavior which led to diabetes.

Feel better now?

You don't seem to have read many of my comments. My good friends were all auto mechanics and racers and I respected them greatly -- one of them has been pictured on the bottom of my website for over a decade. They were a lot older than me and have died.
