Well done. I’m impressed that all three siblings were involved and the adult allowed them to do this. Excellent educational and inspiring moment in their lives. Just really beautiful.
Resetting the mechanism of a full-size trebuchet is, of course, tricky. The world's largest trebuchet, at Warwick Castle, uses walking wheels to wind down the arm.
The dog's a true star. He's always looking down the street cause he can't wait to run and fetch that potato. We don't rly know what happened the first launch cause of an early cut, but at the second launch you can see that he's just about to rush down the street, but the girl beat him to it (3:14). The poor soul is then so distraught by this, that just minutes later at the third and final launch (3:28), he's so confused that he forgot which direction the 3-boochay launches the tater :( Poor soul. I wish him the best
The long part of the Arm Has to be 3,75th the lengh of the Short Part. The sling Has to be excact the lengh like the long Part of the Arm. Thank me later. Sorry for my Bad english, Feel free to correct me
Well, I prefer a 1:5 ratio on the counterweight to release arm and I say that the initial part of the sling where your projectile goes should come down to where the frame connects with the arm and that the release sling should be a bit longer than the sling that holds it onto the arm. It seems to work for me, but whatever.
This is a great project and perfect for my son's high school project. I will appreciate if you could provide with the details of the project, including the measurements and calculations. Thanks
Wow this is kind of US childhood school project unfortunately I grew up in Russia so we don't had any school projects untill the 8th grade when we start studying chemistry
The trebutchet is a catapult, the mangonel is also that of a catapult. A catapult is something that can launch projectiles at a great distance. Catapult is an adjective.
Pretty decent for your science program, kid. I would have put a projectile channel on there so that the sling wasn't being dragged through the mud, and a proper locking and releasing mechanism would be good, but pretty decent. Hope you got an A.
fun fact real trebuchets actually had 2 massive wheels on the sides where peasant workers would run like a hamster wheel to re arm the weapon ready for reloading
Sling should be thinner and the middle of the sling should be more of a cup than a folded piece of paper. The hook should be straight and the frame should be higher up for a longer release time for a better spin on the sling. Edits: make your counterweight more of a box and put your weight into the box and put it a bit closer to the arm. Also, your counterweight should be a bit heavier as a potato weighs about 180 grams and your counterweights is weighing around 22570 grams. Just plug in the numbers and yours is around a 1:122 projectile to counterweight balance when it should be about 1:13. Edit 2: make the sling longer and make a smooth plate that goes over the two beams at the bottom of the trebuchet and oil it for the best results from the swing Edit 3: don’t forget that your sling shouldn’t have much of a clean, circular rotation as it comes up but should be a bit jagged and kind of like trying to draw a circle with your eyes closed. Also, I notice that your frame that’s holding the arm in place is kind of rusty in a sense that it’s holding back a bit on the arm so I would oil that. Also, you should cut the arm in half to release a looot of weight off the arm. That should help for a faster swing.
This takes me back. I'd have the pivot point more narrow so as to put less stress on the axle? Anyway, that's how I did mine. I didn't have an articulation which set me back a bit. I just threaded a cinder block onto the arm.
"Like this..." is painful to watch. Where is the sled for the sling? Why is it unnecessarily wide? Not a hook for release, but a stable post with an adjustable rope. But, you didn't make your A-frame out of one piece, so props.
Actually, most trebuchets would use human bodies to throw over walls during sieges before they sent up the ladders or towers just to spread disease. And trebuchets weren’t used for taking out walls. They don’t physically have enough force to do that. Except the warwolf *haha.* If you wanted to knock down a wall, you should be using a tortoise for that.
No, not "actually" even remotely true on any point. Trebuchets were used as siege weapons many times throughout documented history with varied success. They could most certainly take out walls, the "force" is irrelevant. As for your other point; it has been deemed implausible by historians that human bodies were ever thrown by catapults in an attempt to spread disease.
@@shockwavesteve They didn't. It's not fact in any sense of the word. Do not act like it is just because your stupid high school history teacher told you that in bum fuck nowhere. Google it and educate yourself.
Bollibompa “During the Middle Ages, victims of the bubonic plague were used for biological attacks, often by flinging fomites such as infected corpses and excrement over castle walls using catapults. Bodies would be tied along with cannonballs and shot towards the city area.” 😘
@@shockwavesteve Check the sources for the Wikipedia article you just quoted from. Yes, it is an interesting idea that the Mongols hurled infected bodies at the siege of Caffa and Mark Wheelis sure popularized that notion. There are even medieval illustrations of it supporting this idea. This is however disputed in recent times for many reasons and Matthew J. Broughton puts it best: "Did bodies fly through the air with the greatest of ease? Did these bodies start the Black Death of Europe? It seems unlikely that this is how things happened. Rats would have moved freely through the walled city of Kaffa, and the fleeing people probably took those rats with them in their ships’ cargo. This most likely is how the plague came to the Genoese and to Italy and ultimately the rest of Europe." The actual historical accounts of this happening is very scarce. Wheelis uses one secondhand source in the accounts of Gabriele de’ Mussi. One need to both apply the Principle of Parsimony and understanding the political aspect of these claims. The hatred for Tatars and wanting to paint them in the most vicious of lights seems motivation enough to embellish. Moreover, the use of a human body as a vector for spreading disease is not as feasible as compared to the simplest explanation; rats being rats in the filthy squalor of medieval Ukraine.
