They auto-close when the top hinge is more to the outside then than the bottom hing, or the whole frame is tilted towards the inside (where the door does not swing into). You can try adjusting the hinges with a tool. In an ideal situation everything is level in all directions.

This hurt my brain. I guess we envision inside and outside on different sides. Not sure if this is any clearer, but the door will close itself if the bottom hinge is offset from the top in the direction the door opens. Picture the angle of the bottom of the door when it is open 90 degrees and it might be easier to visualize why it falls shut.

Yes, we are saying the same :)

I am the OP of the referenced article... I'm here because I saw a large spike in interest in the article and traced it back to this post. A few responses to these comments, if I may, without getting abuse...

* Of course I was having fun with the "North America" comment. And the Coriolis Effect did in fact come to mind when I wrote it.

* The article was not "advocating" for pictures to be hung on wires -- or flush against the wall for that matter -- but was rather a response to some inaccurate/misleading advice on other websites about how to hang pictures flat against the wall. There seems to be great interest by others in doing that, as it is one of the most frequently-used search terms that link to my article.

* Specifically, some sites claimed that the forward tilt had to do with the weight of the frame, and I thought I would do laypeople a service by demonstrating that the weight has nothing to do with the frame's equilibrium position.

* I enjoy recreational math, and this was a situation that (to that point) had not been answered on the internets. If it's TL;DR to others, so be it.

* Finally, while iteration is indeed within the capability of computers, it is not within the capability of the wordpress on-line calculator plug-in that I provided for the convenience of readers.

In any event, Happy Monday, HN, and thanks for your interest. - Craig

Yes, however the discussion is more valuable than that. I once bought a framed poster at a garage sale and discovered when I got it home that it had a steel plate across the bottom of the frame. I thought it a bit of over engineering for adding frame support (it attached to the back of the frame with machine screws) but when you hung the poster it hung flat against the wall. I took me a couple of weeks to figure out…

> I took me a couple of weeks to figure out the person do did that was moving the CG of the framed print closer to the wall which made hit hang nearly flat on the wall. As it was at the bottom of the frame, it also moved the CG lower, which also helps to reduce the tilt, even if the CG remains a little bit to the front. > When reading the referenced article I realized it also allowed for an arbitrarily tightly stretc…

It was a plate, probably 3" "tall" and as wide as the frame, attached in four places at each of the corners. As a result it held the frame rigid (much like a corner bracket would). If you pulled the top toward each other, in addition to the top bar of the frame resisting that pull, the bracket would resist and attempt to make the bottom/side angle less than 90 degrees.

Pictures and paintings were supposed to tilt forward a lot, to make viewing them better. It fell out of fashion. Look at old photos from inside homes, and you see wall paintings very tilted.

The old houses of the people rich enough to own paintings in the past had much taller ceilings than the houses that are affordable now for most people, while now anyone can have a copy of a famous painting or a cheap original painting or photograph. So it was normal for the paintings to be hanged at a place higher on the wall, so you had to look somewhat upwards to admire them. In this case, a significant tilt forwar…

Exactly, and when photos and paintings became affordable for normal people, they would hang them in the same style as the rich. Even if they didn't have tall ceilings.

This sentence is very funny to me: "Most people in the Northern Hemisphere hang their pictures on a wall." I guess OP did some research but perhaps wasn't exhaustive and didn't want to generalise to below the equator. People write funny and quirky things. I'm glad things like archive.org exist to save the quirkiness for future generations.

Or maybe the author is not discarding the hypothesis that, in the southern hemisphere, frames tilt backward due to the Coriolis effect ;)

I've heard that at the equator, people put pictures on the ceiling; they're held there by centrifugal force.

OP kinda has a point though they did not phrase it effectively. From my experience, here in Asia we generally don't hang paintings/drawings/anything on walls. Most framed images are photos and these are more likely to be placed on shelves, tables suchlike.

TIL Asia is in the southern hemisphere

There are many who place frames on top of mantles, piano or other objects....

Jubal called out, "That house on the hilltop--can you see what color they've painted it?" Anne looked, then answered, "It's white on this side." Yes, in this case, it's quirky and possibly endearing. When people feel like they need to document trivial comments by writing "Edit: typo", less so.

Nice Heinlein reference. That particular concept stuck with me after reading SIASL
