I love when you post a new video, I love all your videos even if I don't think I fully understand everything at first it's always so interesting, the concepts, the math, the music, the visuals, everything is so entertaining and peaceful, just pure chaos analyzed and presented as a lesson in physics. I need more knowledge I'd love for you to do more complex videos with increasing difficulty in understanding and lean more toward the philosophical implications. I love how your content is such a beautiful challenge in my level of understanding it's something a college class could never achieve and you make it look effortless.

[@EugeneKhutoryansky]

[@Chrisallengallery]

Is this why bullet exit wounds are larger that the entry point?

[@EugeneKhutoryansky]

No. In the video, the tower is hollow inside. In bullet wounds, the pressure from the impact tends to cause a cone of force.

[@madisondampier3389]

The size of the entrance and exit holes are a careful balance between the remaining energy in the projectile and the structural integrity of the demolition target, a brick wall uniquely collapses under its own weight, so the damage caused by the entrance hole is enough to cause instability in the exit wall before the projectile can hit it, allowing the slowed projectile to still cause more damage to the exit than the entrance at greater projectile masses. Human tissue is more structurally sound, without the entrance or exit tissue relying on the integrity of the other, but the compression of tissue behind the exit due to the impact carries more energy from the bullet into the exit wound, creating a larger hole with somewhat explosive force. Compared to the brick wall, the bricks launched from the entrance hole do not carry nearly as much force from the projectile, as blood and tissue does from a bullet traveling faster than the speed of sound.

[@dougdouglas2112]

Let's find out. Stand against the wall and I will fire a dodecahedron at you from different angles...

[@Leviathan268]

I believe it has more to do with tissue compression as Eugene and the other commenter mentioned. There are also the effects of bullet tumbling and "mushrooming". As the bullet enters its tip is normal to the skin, but bullets are apt to rotate and may exit sideways. Also certain types of ammo are designed to deform into a mushroom-like shape with a blunter tip, or even tear open at the top and sorta spread outwards radiallt. The latter are the so called hollow points we often hear about in the news.

Cool, I have heard of a similar experiment back in 2001 involving two towers.

This is a unique concept! It's amazing how the results can vary greatly depending on the dodecahedron's mass and velocity and the tower's shape.

Your explanation ignores the bricks that exit the shape along with the projectile. That is one major reason for the larger exit hole.

[@EugeneKhutoryansky]

First of all, not all of the simulations end up being used in the video - just the ones that have interesting results. It takes the physics engine several hours to create just one of these simulations. Then, it takes a much longer time to render one of these simulations into an animation. Therefore, you are already looking at over one week just for a few of these examples.

[@smileyp4535]

@@EugeneKhutoryansky wow. I was kidding of course but I'm quite surprised at how long it *actually* takes, isn't there software that can compute at least some of these simulations in real time? 🤔 I know of course it takes time to, plan, record, edit, simulate, final scripting, narration etc etc, it was a joke at how easy a video like this makes it look when of course it's actually the result of hours if not days or longer of work. Very impressive 👌

[@EugeneKhutoryansky]

Thanks. How quickly a physics engine can create a simulation depends on how many movable objects are in the simulation. The reason it took so long in this case is because I had such a large number of objects.

Who up shooting dodecahedrons at they towers

[@DamonGarfield]

I wonder if these principals have been used for body armor...

[@blacktigershearthstoneadve6905]

Yes, absolutely. This is actually the main thing about body armor - the way it absorbs and distribures energy over its internal structure. This is why body armor is always layered and never a single solid plate of something. Essentialy you want as much energy as possible to be redirected sideways causing destruction of the armor itself (like in the square example), so less energy will be left for further penetration. The principles shown here on bricks work in armor materials on molecular level.

[@madisondampier3389]

The bricks have a high friction coefficient and mass, and due to the fact that these bricks do not crumble but are rigid bodies that are stacked perfectly, they can withstand a lot more force before they collapse or slide off of each other than normal bricks do. This does not mean that the principles discussed in the video are not accurate statements about the underlying physics.

As a bit of fun, this was fine. But as an experiment, it was useless. Changing the mass and velocity of the dodecahedron will not show any valid relationship as the bricks are loosely bound and take part in the scattering process. For instance, at the beginning, the size of the hole should not change much wrt to the mass of the dodecahedron, but since the bricks are being blown back, the exit hole is much greater due to that reason alone.

[@Talleyhoooo]
