The flywheel coming to a near deadstop left me speechless. such a good representation of the conservation of energy
Yes! Exciting ain't it, how most of that energy was apparently transferred into the projectile?
@@MRptwrench that one unlucky bird hit by the ball will experience all the energy it has stored

Destin! Funny seeing you down here, just finished your video about extinguishing fires onboard a submarine. You and Tom are both awesome - any chance for a collab?
Collab
Supersonic baseball trebuchet?
Imagine, you’re making yourself a morning cup of coffee, looking out the kitchen window hoping to see birds and deer, but instead you see your neighbor building a trebuchet. Thinking to yourself, I wonder if this house can withstand a siege? Also contemplating and calculating on when to return and how long to have borrowed a weed trimmer.
you are awesome and i love this
Exactly. Also, If you decided to leave before the siege I’d advise to still make yourself that cup of coffee but make it in a portable insulated cup, with a lid on it. You might get hungry during your escape from the siege; this is where some ham and cheese sandwiches would come in handy. If there’s time you could wrap the sandwiches in tinfoil or a similar product to keep them fresh, but ONLY if there’s time.
Or you chillin' with your morning coffee and you see random tennis balls flying past and thinking your neighbour's kids are playing backyard cricket. Then you start seeing flying random objects like apples, or even smallish heavy toys and then your curiosity is piqued. And then you hear "Ok that's good but now I must just tweak the string and release a little earlier". "What the heck is going on?"

"That is gonna kill somebody when it lands in boston."
i was thinking 'man that'd be awesome if he put a motor on this thing" right when you said "perhaps i'll put a motor on the crankshaft". can't wait for THAT video lol, thanks for the great content
Exactly my thought, it would be fun to see this supersized, more weight on the flywheel and a motor.. If it's worth doing, it's worth overdoing.
"maybe I need to put a motor on it" Yes, yes you do.
No. He needs to put a BICYCLE on it. Leg power over arm power. Also a finer balance on the flywheel.
No. He needs a motor. Nobody wants to sweat.
And make an even bigger one with an eight-spoke wheel and a heavier counterweight.

I think this is one of your best videos. It's just really interesting to see how flywheels can store energy like this.
I love the way nearly all the energy is transferred from flywheel to ball. Splendid!

But also has pretty good quantity
@@adamhale6672 yes
thank you guys so much ive never gotten this many likes before
Almost like Will Osman, but with higher effort videos
Matt Dumbrill never heard of will osman before
Seeing it almost come to a complete stop when the projectile is released is just awesome and prob one of the neatest things I’ve seen pertaining to physics.
Exactly this,.... we get taught aboubt conservation of energy, but don't really grasp how spooky it can be. Pool balls stopping when they collide with another doesn't seem so spooky, but this? Physics is cool.
The forces on that arm... Yikes...
Kiromos , right! It’s so smooth though that, it looks as if the arm didn’t notice, but when you break it down and understand what is going on, it’s unreal on so many levels the forces on it are and yet so graceful.
This is actually a commonly used method of reducing angular velocity during rocket launches.
@@Kiromos yet human arms plus tennis racket can hit a tennis ball nearly just as fast... If thats crazy then the strength of our bodies is insane!
couple general trebuchet questions: 1) are launches/launch speeds consistent? 2) can you actually "aim" a trebuchet? (i guess these questions apply both historically and for this modern rendition)
Shame nobody answeared yet so I´ll do the honors. The lauch speed of clasic weight/lever trebuche should be as consistent as the weight of the projectile. And yes, siege engeneers would spent whole lot of time doing calculations to ensure the siege trebuche would hit it´s target. You dont want to spent month building one and realising it cant even hit the castle wall (you generally want to go over the wall and land inside). But its also good to know many sieges ended before you could build trebuche since people percieved then as we percieve H-bombs now. You simply lost your will to fight
Excellent! Really. Especially impressed by the energy transfer with the heavier projectiles.
Not going to lie, this was a brilliant demonstration of energy transfer. Hats off to you.
love your videos. ive been working in my own tesla coil for a while now. i was wondering if you could tell me what you think of it? i have vids on my channel!

Thank you for the inspiration and absolutely incredible proof of concept, Tom. Over the last six months or so, I built a scaled-up flywheel trebuchet with an arm diameter of about 16 feet. It almost works and hopefully will be competing at the Rapid City Pumpkin Festival on September 25th. I'll make an actual video of it eventually. Keep up the fantastic work on your channel!
I was really wondering how this idea scales and compares to traditional trebuchets. Given normal material strengths like steel, just how fast could you get a projectile moving? Would love to know how your attempts panned out!
Hey man! I'm from the future, from a country which has a pumpkin festival with a pumpkin trebuchet competition. I wonder how the trebuchet turned out? Did it work and do you have a video?

That is amazing mate. Great job! Really fun to watch.
I love the part where you try to drain the flywheel off all of its energy.
Yea, thats awesom to see! looks a bit surreal.
Feels like the way he is going at it is flawed though.. Won't simply increasing the mass have diminishing returns and never truly siphon it all?
It’s like watching yo yo despin weights release on a rotating body. It’s almost un-natural, I believe the physics but at the same time my brain says no way.
"I run away to stop the highspeed camera" has the same energy as "I move away from the mic to breathe in"
Dude that was what I immediately thought about when I read that text lmao
"I run away to catch that ball, cause I'm Flash".
I mean, high speed cameras have a limited buffer, they only capture about the last 5 seconds of video. Depending on settings and such. So he probably has to run to catch the shot.

Such an elegant design. No more complex then it needs to be and does what its deigned to do happily. Nothing superfluous and arbitrary. There’s something special about something that isn’t designed to be beautiful but is beautiful as a result of its necessary design elements.

Seeing the flywheel almost stop was really impressive. Definitely a bit of physics that doesn't look intuitive straight away.
The weird part is that the whole thing doesn't shake. You could easily put a break on it to force it to a sudden stop, but in that case the whole thing would probably flip itself over, like breaking the front wheel of a bike at high speed.
@@Yora21 all that energy is carried by the projectile. It's amazing, isn't it?
@@traugdor What I am surprised by is how much energy gets transferred. The ball obviously has a lot of kinetic energy already while it's spinning around the axle, but I don't see how it "sucks" the energy from the wheel into itself. Intuitively, the ball should go in a straight line with the same energy it had before separation, and the flywheel continue spinning with the same energy it had.
@@Yora21 that's the effect of the sling section.
0:33 *HE HE HE HA*
The face you make in the high speed footage is mint 😂
Wow, watching the arm just STOP because of how perfectly the energy transfer being "optimal" was really unsettling!
They actually use a similar technique to stop spinning spacecraft
I wonder if he could go just a smidge heavier and make the flywheel be rotating slightly BACKWARD after launching? That would be really weird to watch.

There is a very happy golden retriever hiding in those woods chasing every tennis ball and really enjoying himself
Him standing next to a massive pole spinning fast enough to (probably) kill him is making me nervous.
Yeah his method of securing didn't look too fantastic given that if the apparatus fell laterally the arm would surely break some shit
@@mrbouncelol However the flywheel would have likely a decent amount of gyroscopic motion that would want to keep itself spinning in the same access of rotation. The faster it spins, the harder the machine is to tip over, assuming his cranking isn't rocking it back and forth.
Hah ! You said "massive pole"
yeah i was thinking for gods sake add some cement blocks to a frame at the bottom man the entire video
@@JakeShuf My main concern is the fact that if he trips over or something while spinning it up, he's kinda fucked. Big heavy spinning things scare the shit out of me.
Hi Tom, excellent video. The last part, where you tuned the trebuchet to extract more of the kinetic energy, was a really nice touch, and shows how well you understand the physics behind what you do. Another option could have been to create a semi-automatic trebuchet by leaving it "sub-optimized", and changing the design a bit so that you can feed the balls from the center as you keep turning the handle to recharge it, (maybe an idea for a future project?!?;). Thank you for your interesting (and often amusing) videos.

I like the way the wheel stops when you let it go. I considered using two train wheels and axle to launch pumpkins. I was going to leave the pumpkin still while the wheels spin up to 500 rpm and use a clutch to engage the swing arm. You have an advantage spinning the ball with the flywheel since it starts with a lot of speed before swinging out on the string.
Well done. A mystery tennis ball hit the ISS a few years ago, it must have been Tom managing to increase the speed a bit further. Jokes aside, perhaps you can spin it faster by attaching it to a stationary bicycle frame, spinning it up using the bicycle crank.
Imagine you’re breaking into this mans house, and all you hear is “now where’d I put my trebuchet?”.
"I'm warning you. I have a trebuchet, and I'm not afraid to use it."
all you hear is: "at seven kilograms once the ball is released it leaves a sling with a kinetic energy of 132 joules meaning the usable energy efficiency is just 31 percent"
Imagine being a sheep in a field then getting hit by a tennis ball going as fast as a pro tennis serve.
Would be pretty baaaad

It makes an awful lot of sense... well done. I don't think it would have been possible in the days of trebuchets, but now.... again, well done.🏆
