Being short does have quite a few disadvantages. I'm medium height (5' 8"), so don't have too many problems, but I've used rolling chairs often, mostly because I'm often too lazy to get a proper stool.
And thanks. I'm glad you enjoyed my sense of humour. I have to have one, as you can see. lol
Maybe, Idaho Spud, but the floor and table looks really yellow on my comp and the angle of it makes it look like a child's home-made ladder. I've made many different attempts as a kid (a very short one at that) to make various ladders. According to my mother (who was 4'11" like myself, until she shrunk to about 4' 8" and now is 70) many people thought I was 2 y.o. when I was 5 y.o. and the dr was a bit concerned until he also found out my bio-father was 5' 3". She was always on me to use either a stool or a step ladder, instead of experimenting with different ways to climb like an ape or make ladders. When I had my sons and they began to climb on counters and stuff to reach things, I didn't scold them for it, because I was the one who taught them to do it. lol Try balancing on a rolling adjustable desk chair to change a light bulb. I've done it many times. Can't say it is safe, but anything that works is good enough. Who knows? I could have been a child's attempt at a home-made ladder. :lol:
Yes, that top pencil does look ready to fail.
Yup, it's a bit harder to take in, in a static photo like that. It took me a few seconds to process that they were all tied together and represented something that stayed that way more-or-less securely (until that top pencil snaps).
Mriana, perhaps you would have wondered if you had seen it in person. The picture is a little dark on my computer, and so took me a while to figure the whole thing out. I only recognized what it was supposed to be immediately because I've seen that type of thing many times before.
In any case, I enjoyed your sense of humor in your first post.
It doesn't fall because the objects are perfectly balanced around their point of contact. Well, the center of gravity of the whole doesn't have to be perfectly balanced on the edge of the table, but the closer you can get it to the edge, the more impressive you can make it look.
In this case, the head of the hammer and the head of the wrench are the heaviest parts of the ensemble. Since those are under the table, they bring the center of mass a great deal back in that direction.
We're generally bad at estimating masses of relative things, when they're made of drastically different-mass materials. With most hammers, particularly fiberglass ones, the head is several times the mass of the handle. That's kind of the point: getting as much mass as possible further up the lever, away from the fulcrum, increasing the mechanical advantage without increasing the total mass that we have to hold.
The forks and wrench are similar. We tend to think of wrenches as one, solid piece, about equally dense throughout, since they're made of solid metal ... but look which way the head is facing. The forks are relatively light, since they're very thin. Our brains say, "Well, that thing is made out of metal, and it's so long and wide," ignoring the third dimension.
Interesting. I didn't wonder why it didn't fall, but I am confused as to what it is and what it's purpose is. Now I know what it's purpose is, but I guess I fell outside the box due to not wondering why it doesn't fall.
I recognized it immediately as one of those constructions that are intended to make people wonder why it doesn't fall.
It took a few seconds to see why it doesn't fall.
Is it a ladder for us short people to get up onto the table? There's a wrench in the works though, because I'm not sure if it would hold me. lol Other than that, I'm really not sure what it's suppose to be, so fork over the tools and I'll make a better ladder. ;)
