      @@christofferrasmussen6533 I repeat, the best one was "bridge it", search it on internet.
      You had a set of complex levels and free money levels in which you could set free your creativity, the graphics were really good for that time (because it was made in collaboration with nvidia).
      I made all kind of bridges or any kind of kinetic structures, from bridges that submerge under water when a ship pass or a huge wheel of fortune or any type of mechanic structure.
      The construction method and parts where also better than current bridge games.
      But as I said, I would have love a more general physics game, not just related to bridges.

      Brertt not for the level of load you would expect in his situation they aren't; at least asuming his house isn't a five story steel, brick and glass monstrosity. designing an arch that can bear a few thousand pounds is possible with nothing more than a rope and some rocks. People have been building arches using these techniques for more than a thousand years, sometimes without any maths involved at all. The romans never had any computer stress modeling or materials science to tell them how much load their substrates could bear, but the aqueducts are still standing today.

    I had a great education in Civil Engineering at Heriot Watt University but I can tell you that I Learned a lot via the models used in your videos. It seems so clear using chains but I never heard of that analogy before. What you are showing is that as soon as the arch blocks see eccentric loading then the joints try to go into tension and rapidly fail.

    I used to take World Civilizations back in College and my professor briefly mentioned how the Romans were so proud about using them but he never explained why (or maybe he did but I wasn't paying attention).

    I did not expect to learn something today, especially about bridges, arches and chains, but this was nice

    I like these videos because they are about the practical nature rather than a bunch of maths.

    At first i was like, this is a stupid video for kids but then after a short while i found it very informative and helpful, especially with the hanging chain examples.
    9/10 for this video

      With the simplicity and good examples i can't see many videos with this quality. For small chanel it is even harder to be refine as this. I am giving them 10 of 10 :)
