This is the least informative video on trebuchet tuning I have ever seen. Yours must be dreadful.

I feel like it's really a lost opportunity whenever you explain an element of the trebuchet but didn't actually show it on the screen, instead playing the default trebuchet shooting animation. For example: When talking about the arm length, you can lengthen or shorten the arm of the trebuchet, let it shoots, and see how the shot would be different with the change.

You are so right. I’m shocked at all the meat riding in the comments - even though I understand the elements he’s talking about quite well after this poor presentation I felt like I knew less than when I started. He makes no effort to explain anything - it reads like the worlds most useless Wikipedia article.

0:06 "Stop looking at our plans, woman. You don't even get a hard hat."

At 1:12 minute-mark you say that there are only four things you can vary: "Lever arm length, height, counterweight weight, and fulcrum position." You are missing half! You can vary the counterweight height, the sling length, and the angle of the pin on the tip of the throwing arm, as well as the CG of the arm. The counterweight height is how far it hangs from the counterweight axle on the arm. A counterweight height of zero would imply a fixed counterweight. Ideally, you want the counterweight to hang as far down as possible without hitting the ground, but in the case of trebuchets like the one at Warwick the box has to clear the winding axle for the treadwheels. You can also vary the CG of the throwing arm by tapering it or adding "counterpoise" weight. Some medieval drawings feature an added ring of weight on the butt end of the throwing arm (in addition to the counterweight box), which was probably meant to bring the CG of the arm closer to the main axle even before the box was attached.

Both sling variables (length and pin) are dependent on your choice of counterweights arm length, and projectile size. My point was to state the unconstrained variables you could optimize the design. Sling variables are highly dependent in the design process. Counterweight height is a variable I mentioned as well as usually being dependent on lever arm length and height in traditional trebuchet designs. The CG of arm is also a dependent variable on the variables I mentioned 🙂

My experience with the "rings", "heavy short arm" is that that mass slows the arm down. It's just more mass that has to be accelerated. I think the lighter the upper hanger arm and short arm are, the faster the throwing arm will be.

So did I get this right? The ideal payload to counter weight length is 3.75:1, 4:1, or 5:1 and the ideal projectile mass to counterweight mass is either 1:75, 1:100, or 1:133. If so I need a bit more of a clear answer from this.

Every machine is different, and those numbers mean nothing. Too many factors to say "this is the best way", or "this is optimal". These machines are purpose designed and the only thing that matters is can they forcefully hit the target repeatedly and not fall apart, from a range that the crew would not be killed by arrows. Now with Sport Catapulting and Punkin Chunkin the machines are still purpose built, and everyone is unique. No formula or equation can tell you the best way to build any of them.

3.75:1 beam ratio x PSSSHHSHHS' rule of 20 means that CW to projectile is 75:1. Just seconds prior, you say the mass ratio should be 133:1. These rules are not in agreement. So, which one is it?

@HickLif3

​@@MTEXX I think he just meant that 133:1 is the widely known or used rule jsut like the 4:1 or 5:1 lever arm ratios are the most commonly used. But the math says it isn't the best

Maximizing potential energy is crucial. Construcing trebuchet so that the weight falls as vertically as possible, instead of swinging, increases efficiency. Wheeled trebuchet end up being the most efficient.

Can I please have the counterweight be perfectly motionless after the shot thus converting all its potential energy into the kinetic energy of the projectile? Or am I asking too much

putting the swinging fulcrum on wheels allows for a more direct vertical drop and increases force and velocity of projectile

@@lordbalzamore7692 Two main reasons: 1) when it's on wheels, the trebuchet will roll back and forth such that the counterweight can fall straight down, which is more efficient since else a small part of the weight gets transferred to the throwing arm (also see kzread.info/dash/bejne/faR6ttt-XdrPftI.html) and 2) it reduces stress on various parts during the throw and doesn't kae it want to tilt over.

2:32 Donald B Siano is educated and ignorant. Everyone who knows anything at all about trebuchets knows that they need to have wheels!!! The wheels make it so all the kinetic energy of the counterweight can be used to move the projectile. If there are no wheels the extra kinetic energy will be absorbed by the trebuchet.

OK, Siano later came out and said that he made some invalid assumptions. Pfsshthpok's Rule is a guide based on observations of a number of trebuchets and breaks down at extremes of mass ratio or leverage ratio. Da Vinci came out with better numbers involving square roots. You could build a treb based on the info in this video and it would doubtless work well, but it wouldn't be "perfect".

good video hope you keep update :)

You know I'm impressed with the fact that you have a degree(s) in engineering and you can throw around all the big equations and all, but do you really think the folks, back when these were designed, used the same method, I think not. I think, if you can even do it, that you go back to basics and design one, as our ancestors had, and build one.

Have you watched video's from the Shadiversity KZread channel? There is amazing content about medieval weapons and architecture! You must watch the video about whether the castles and fortresses in the LOTR trilogy are historically accurate. In my opinion video's that are educational and entertaining at the same time makes a KZread Channel achieve cult status. So channels like Wendover Productions, Real Life Lore, Shadiversity, Geography Now and so on. Keep creating this amazing content as achieving this cult status is definitely possible for your channel even though difficult and takes a lot of research. But it will gain you MUCH more respect than people like Logan Paul who just simply make video's of themselves fooling around acting like idiots ( videos that do not take much thought/planning or effort). Also do not feel pressured to get a video released every Monday, it is OK to be delayed a couple of days because the content of your channel is top quality and I think your viewership will understand the effort and time required for even short videos like yours. So they will understand it. Even Real Life Lore have been delayed by a day and Wendover Productions have reduced their output from a video every 2 weeks to a video every 3 weeks! By the way these are the list of KZread channels that I think have attained cult status, your channel is on its way to join this list!
