The video explanation is wrong. Your understanding is based on a flawed idea. It’s not compression. Or tension or anything. The first example the paper fails because the ends are not fixed in place. The second example it is much stronger because it is essentially fixed in place.the ends cannot move more outwards.
I'd have to agree with Mook Faru, tension requires an affixment whereas compression does not. I suspect a major reason many dams use an arch shape is that concrete is stronger in compression than tension.
Your video about dams is so valuable, I would like to translate it into German and make it a video for my students. May I ? I could then send you the video, if you like.
Hi@@billybobby5612, I tried to play with words, but obviously wasn't that successful :-l. However, I converted and showed your video: the students were so impressed, they wanted to know your RU-vid channel.
Mikel Sopelana Durango it isn’t a joke, it’s saying that the yt recommendations are often strange, the reason u have seen it manny times is because allot of ppl have the same problem

(Timestamp: 1:27) My answer: I think that the bottom of the dam will collapse first because it will be held under the highest pressure, as shown earlier in the video (0:30) "The magnitude of that pressure is proportional to the depth", where the bottom of the dam will have the greatest depth. Edit: Accurate response, 5/5
I assert that the arch dam collapsed because the human threw the marbles against it. Demonstrating it in such slow motion invalidates the intention. Perhaps your arch dam was far more structurally sound than you expected?
