The Spooky Science of Wedge Powered Objects
HTML-код
- Опубликовано: 23 дек 2021
- Welcome to another episode of Scrap Mechanic! Today I am doing experiments with wedge power! Wedges can actually provide power to objects if used in a particular way, but how powerful can wedge power really be? What more is there to understand about wedge power? Hopefully these rigorous scientific experiments can shed some light on this mysterious power.

It seems, in conclusion, that wedges provide a lot of speed, but not a lot of torque. Having wedges on the opposite side of the pipe-pieces provides more torque, but less speed (because of friction).
Solution is "wedged bricks" : No engine car (Ducks V2.0)
gas engine, not electric
Make a train with it multiplayer
Or you could say wedge is like a gas engine
yes, the stats are never balanced but always work with each other
I love how much wedge-gang has evolved considering that it started as basically a meme!

I've always been #BrickGang until today, but after this i don't know what to say
@@alessiobenvenuto5159 shame on u brick gang
@@namish2727 only now i could see the true power of The Wedge™, i think imma switch team today
I am a programmer, I can explain how this works/why this happens (theoretically).
All objects have a hitbox and a boundary box collision. Boundary box collision is separate from hitbox as hitboxes is a cube that depicts the X,Y,Z of potential collisions (collisions can be any shape inside the hitbox), this is what the boundary box is for, to visualize that. For physics to work, when one objects collision is breaching the collision of another object, the 2 objects repel eachother from the point of where the breach occurs. This is how objects can "touch" without overlapping. The closer to center of mass, the more force they push away with. A 45 degree wedge is the closest you can get to center of mass because the center of the boundary box is already at the surface rather than inside the geometry (collision).
What is happening is that the 2 objects are constantly having a breach and are trying to exit from being inside eachother. The wedge is being pushed back and up while the top of the wheel is being pushed forward and down. Due to the hinge, the top of the wheel can only be pushed forward OR down, not both. With the wheels position being locked there, the wheel cannot exit from being slightly inside the collision of the wedge, meaning normally, the wedge would be the one to exit the intersecting collision. . . except while the wedge is being exited out of the wheel, the piston is pushing it back inside the wheel collision as soon as it exits. This then causes a constant loop of repeating the issue thus causing the process of "exiting" to constantly keep repeating. . . resulting in the top of the wheel always trying get away from the being inside the wedge thus creating constant motion due to the wheel constantly trying to escape the intersecting collision.
That makes sense, but why does it go faster when you put mass far from the wheel?
@@The_Wosh Different center of mass.
The big difference tho is making sure nothing is colliding with the sides, like something on the wheel’s end is not colliding with the side of the wedge.
also the piston has no clip properties
That was actually really inreresting to read, and makes sense. Thank you for that!
And why don't you have more likes, these are some of the comments that you want to read
@@slycooper1001 i think you mean the piston POLE has no COLLISION. The piston base has collision but since the end is so far out, that really doesn’t matter. As far as the game is concerned, the wedge is floating in space semi locked to an axis trying to hover to a specific location more or less.
But now you have me wondering how the wheel would react if you put a block behind the wedge inside the piston pole and how that would mess with collision. I would assume it would make the wheel spin even faster.
Reason:
The block would provide collision to push the wedge back into the wheel in addition to what the piston is already doing, theoretically making that "pulse" I referred to happen even faster/more frequent. The alternative is it would have the opposite effect and help the wedge settle to the position it's supposed to be thus accidently "fixing" the glitch. But either one is possible, and that's EXACTLY why I am curious! O.O
Instead of one piston for 5 wedges, what about 5 pistons with 1 wedge each? I think they'd be able to adapt to axle movement better
Yes but lag
I thaught the same when scrapman said I got a idea but he placed the same contereption upside down
He already determined that pushing force has no affect, but knowing Scrap Mechanic, it could be worth a try.
What he could do, is to replace the pipe pieces with wheels, yes, frok the experiment the pipe pieces rotated faster, but may have less torque, and the wheels might be the other way around
@@supernova6742 the thing is, to get any useful speed, using pipes might be necessary as it basically acts like a gear. Since the wheel is sharing a shaft with the pipes and the wheel is bigger, the car will go faster with the same amount of rotations. So probably applying the power directly to the wheels would give it more torque, but less speed.
All that would be true if logic applied here but we're talking about Scrap Mechanic so all of this is probably false
This "Wedge Glitch" could potetially be usefull for making infinite fuel cars in survival🤔
Edit: although you have to mad to use it as your only power source.
The only issue is that this will be patched soon.
@@treemot2417 why, this seems like a bug in the physics engine and they are notoriously hard to patch, the devs also said they do not care about this kind of stuff
Wedges aren't in survival - you'd have to blow up a warehouse to get them. By that point fuel is cheap and easy to get.
@@izakomandaz2895 thats true and engines are a lot more faster
piston engine but much simpler
At this point, wedges are so powerful that newton himself agrees that they aren’t affected by the laws of motion.
*physics 100*
Physics 100 is 100%
wedge power has even gears scrapmans version has 2 gears the slow and the fast
wedges are more advanced than before
except, he didnt use blocks the proper way, in which they are better than this type of wedge power
He got sent packing by the bloody wedges.
12:07 looks like your wheels are spinning in opposite directions which would make sense since you should need wedges on the back of one side and the front of the other side to make both wheels spin the same way, but then it worked so who knows?
Through my own testing depending on the orientation of the wedge and how it presses into the wheel it will either choose a direction or it can be persuaded to go a set direction.
I love how someone probably tried to make a braken system, and they just started going quicker
So alt title: wedge king gets confused by the physics of his creations
Also wedge powered race for MM?
i hope kan experiments with this but with blocks, cuz if u use them the right way they are more powerful and can create more speed, they cabt go up hills tho unless its a very shallow angle
YES!!!!!!!!!! wedge race!!!

You should test Duct Corner power. Curve Crew cannot be left unnoticed...
OOh God 160 likes in about a day.
Oh snappppp
@Yurpio What? No no no, you got me wrong. Curve Crew worships Curves and Duct Corners. Smooth Gang favours low-friction materials.
im both curv gang and wedge gang i guess
@@eagleboi3593 Wheres the love of concave wedge?
Doesn't work sorry😅
The guy who created the Wedge Powered Car deserves serious Wedge Gang appreciation
but what about the guy that invented block powered cars and the guy who improved the design (me) wich are more powerful and speedy
i think the main problem with your wedge powered car is the weight due to its overall size...
also potentially because doing it from a pipe to a wheel is less effective than direct wheel contact with wedges? scrap mechanic physics are confusing tbh
Since when has physics in anything isn't confusing?
@@robbieaulia6462 i guess theres some bias from me because im also an engineer with a hobby for smithing
@@robbieaulia6462 I agree and Scrap Mechanic also has stupidity on top of that, hence the wedge glitch.
I think ScrapMan need to try direct wheel contact, i think it will cause more torque according to more polygon faces being touched per rotation (also more wheels is probably worth it)
This really goes to show that wedges are superior to bricks.
Not superior to pokémon

I wonder do the wedges work similar to gear reduction where more wedges = more speed but less torque, and less wedges = less speed but more torque?
Not exactly but no-ish
Less wedge = less speed more torque
More wedge = more speed less torque
So kind of but you are inversely correct (you switched the two)
@@thefaulnt3562 You literally typed the exact same thing as him
Your wedge science basically discovered ⚙️ gears. You could add wedges to the top coming down and you could have each side having multiple pistons on different buttons, one being bricks for brakes, different wedges hitting from different extended piston lengths, could have your pistons pulse in and out to give you a boost. The gear possibilities are amazing. The workshop should fill up.
I was an OG Wedge gang myself, but not from your gang. I was obsessed by Wedge way before you because how professional Wedge is, then i realized that im not the only one who thinks the same so i joined ur gang. So this video is basically a treat for me
17:55
I was really thinking you're gonna put another wedge up there. If top wedge works you can even make a row of wedge powered axles since its a lot more space efficient
I have a theory.
1)The faster the wedge spins something the less torqe it has wich explains why the wedge powered car™ is slower but it moves.
2)you put pipe-pipe-pipe-conrete on your testing wall but you didnt in the wedge powered car™.
In conclusion i feel like if you put less wedges on the rear shaft the car will probably move slower but it will have more torque.
Ill boot up scrap mechanic and see if my theory works.
so, does it work?
@@yummersans8426 I am still testing but right now the tests have come back negative.
I need to figure out why is the phisics engine is freaking out like this.
@@marcy_0267 I think this whole mechanic works, cause the wedge makes a little bit of contact with the wheel or pipe and the wheel/pipe tries to escape with the touch point and gets a little bit "floppy" so it looses the contact and hits the wedge again.
The suspension on his first car compensated this effect, so the pipe didn't get so floppy and the force was to low.
That's my assumption, which could be the reason, why one of the fastest tests on the wall produced dust and clearly bounced of the wedge.
It's only my theory, I'm supposed to buy scrap mechanic, only to verify this behaviour.
Sry for my bad english, if something is unclear, let me know and I'll try to explain it in another way^^
@@marcy_0267 I managed to make a car that moves decently quick. It all depends on how you orient the wedges and push them into the wheel. I managed to make a forward and reverse with parking gear all in one package. And when I say "decently quick" I mean if you get off it while it's powered 'pistons engaged' your not catching up to it... Without a faster vehicle. also it is by no means light.
As a person who is learning game-development, I can tell:
Every object on collision experiences translational and rotational forces. The translation forces cancel out because they are on same entity, so the rotational forces should also cancel out, but due to the nature of collision correction the linear force from the piston gets calculated into an unpredicted rotational force on the wheel.
I think the double speed system acts kinda like a gearing system in a way so it should increase torque but decrease speed, also you should add a 3rd set of wedges on the top for a 3rd gear instead of a break, and maybe you can fit a 4th gear in the future by lifting the creation somehow.
10:10
I think that this is an absolute magnificent of a moment to consider. You can have gears. With a bit of logic, you can have 1-5 botons forward an 6 backwards.
honestly why dont we just make generators like this IRL? free eco freindly energy smh
no things are bouncy enough for that
it wouldn't work because the government is brick gang smh 😒

@@kaot1k blocks are actually more powerful and faster than this, but he didnt use them the right way so scrapman couldnt have known
@@beaclaster indeed
This shows how much fun people had experimenting with real life physics back in the day! I guess the same still applies now with some aspects of physics, like quantum mechanics
In your build the key factor I think you were forgetting is the weight on the sides of the axel. It had been shown to make it better in your testing so it might make sense to try on the car.
this
Imagine what glitches will appear when they add the dragable slopes
Maybe test if the piston being on one side (like on the wall) gives more power than when it is in the middle of the wedges.
This is what I was thinking.
I would love to see a special episode one day where ScrapMan tests weird scrapmechanic glitches like this in real life.
I don’t know why but this wedge science brings me so much joy.
So this is FREE INFINITE energy?
Here's my question. . . does this work in survival?
If it does, this is TOTALLY going to break the chapter update xD
What about concave wedges?
Also bricks are definitely reverse: go backwards & are slow.
It's incredible what new energy sources can scientist and researchers discover with the help of modern technology! We're on the verge of a breakthrough in science and engineering, and it's even 100% eco friendly
I never knew i needed to see a 'wedge wedge tank, powered by wedge, made by wedge, for wedge, inspired by wedge, brought to a channel near you by wedge'

Yes
We need more of wedge power! Idk... made multiplayer monday with this concept? WEDGE POWER NEEDS TO BE EXPLORED MORE!!!
I think this is because of collision physics, when the wedge is shoved into an object on a unpowered bearing it tries to push both objects away from each other, and the bearing converts x/y velocity to rotational velocity. It doesn’t explain why the direction changes with the weight (somewhat randomly as well).
Merry Christmas !
merry christmas scrapman
"Hey, what kinda engine does your car have?"
"Oh, just the 45° standard wedge."
Merry Christmas to u guys and happy holidays
ScrapMan is learning the difference between Torque and velocity. Next task is to build a manual transmission.
thats so insane amazing work with that glitch
Merry Christmas to everyone
I sure hope they add wedges to the survival portion so you can make a wedge-only survival series, replacing as much stuff as possible with this spooky science
he has ascended his knowledge of the wedge
I just did a quick test and this does seem to also work with the wedges you can make in the craft bot ( the curved ones that I don't remember the name of right now). It also works with level 1 pistons, which means that, to some degree, it's survival mode capable.
those are not wedges tho
but curves consist of lots of corners hmm
blocks are more powerful and create more speed he just didnt use them the proper way.
@@spacewalk3046 Hmmm interesting.
Well that's really interesting. It seems like part of the effect might have to do with bending through the bearing. Makes me think this is just a slight repackaging of the same simplification flaws that led to the suspension glitch.
I attempted a sort of tool setup with this Glitch. Using a drill or saw on top of the wheel (without additional blocks) gives a result, similat to using a gas motor on mid power level. Another step towards motorless survival
It would be cool to have a special episode themed around science and explaining wedge power mechanics, showcasing each aspects of their weird behavior. Maybe you could collaborate with someone who knows how the physics work.
PS: Challenge idea, create vehicle that moves at walking speed and put stuff on it as it moves ahead without you through obstacles. Whether the player manually or the vehicle automatically avoids them is optional. The fastest time wins.
I love Scrap Mechanic's pyshics
happy christmas eve!
More of this please
Almost thought this was a Graystillplays video, it was a perfect example of "We don't need physics where we're going".
A graystillplays fan, i see....
A race with wedge powered cars would be so cool
Thanks to this video I have now made multiple prototypes of survival vehicals that use wedge power, including a large mobile base with independant suspension at every corner and powered solely by wedges. Soon I'm going to make an even larger mobile base with more wheels and more wedges. Oh, wedge power tip, don't do a weird pipe axle, just put the wedge-piston right on the wheel.
I definitely would like to see another one of these videos on this.
I definitely want to see what happens with more pistons, does the force do better spread evenly, does allowing the extra mass to flex offset to the bearing allow for more speed?
Also using triangles directly to wheels, since the original wedge car used it I wonder if it'll give more torque?
Would applying the triangles sideways to the wheels be a better brake?
Someone also suggested individual pistons to each triangle and also that one of the wheels my be spinning backwards? And that's why it won't move from a standstill on one but idk.
Also what chaos comes when you turn down the physics?!
👀💥
All the while the scientific community is so focused on the new space telescope, and solid state batteries, when Wedge technology is here and NOW! Wedge Power is the future!
alternative title:
ScrapMan discovers the difference between torque and speed
I wonder how it would work if it was all wheel drive. And this would be a really cool multiplayer Monday race, you all build cars that are powered like this preferably with wedges but it doesn’t have to.
14:18 when he did something i was thinking about hahaha
Scrap Mechanic science time! I noticed in the original wedge powered car you showed off before the wedge was pushing directly against a 3x3 wheel vs a 1x1 pipe on this vehicle, and it made me wonder how radius affects torque vs speed and how it compared when loaded vs no load. TL;DR - 5x5 wheels are better for most practical uses, more wedges = more torque/speed, and driving a smaller radius wheel once you're up to speed doesn't really work like you'd think it should. Also pipes are weird.
I did some testing on my own and found that 1x1 pipes are definitely the fastest but they do not have great torque, while 5x5 wheels aren't fast but have a lot of torque. Which is as you would expect. However, when loaded things get weird. I built a simple vehicle out of wood with 2 pipe, 2 small wheels, and 1 large wheel, all connected to each other on a single bearing so the large wheel is the only one touching the ground, and each with a single piston pushing 2 wedges into it from the back. The first thing I noticed is that pipes spin the opposite direction than you expect under load - I had to flip my wedges upside down to make them go forward. But even with a pretty small, lightweight vehicle, pipes alone could only barely get the thing moving. Small wheels were also kind of weird in that sometimes they went backwards or stuck in place and sometimes they moved forward. They were able to get the vehicle going a little better than pipes, but not really. Large wheels are definitely where it's at, they got the vehicle going no problem, and had even better torque/speed when I doubled up the pistons (one back, one top, pushing a total of 4 wedges). This is probably the most practical way to make a vehicle move, especially as they get heavier.
One other thing I tried is that because of my setup (with all 3 sets of wheels connected to each other) is that once you get it going with the large wheel, I could toggle on the others in tandem. Adding small wheels did nothing, maybe even slowed it down a bit, but adding pipes did speed it up some. Not a huge amount, but noticeable. However, the main thing I wanted to try is switching to pipes once I got up to speed, like using a higher gear, and it didn't really work out. It sped it up a little bit at first but then lost speed fairly quickly. It didn't completely stop for a little bit, but it didn't work as I hoped. I plan to do more testing when I have more time, and will edit this comment with anything new.
Merry Christmas eve scrap man i watched since before the explosive canisters and pistons were in the game
newton’s first law of wedgecanics: “i have no idea how these things work but they sure do like to make circular things spin”
If I remember correct, piston speed determines strength, not the distance slider. Think of it as changing a springs length as opposed to a springs “speed to extend”.
You may get more speed from the car if you set your piston speed higher, but you may want to remove the gap between the wedges and axle (make them touch always), otherwise you may get some axle slapping, and potentially clip straight through.
Looking at your testing explains why your wheels weren't going fast in your creation.
Remember "farther away from the pressure point-it increases the speed"
The four wedges had blocks stacked before you put the bigger weight on.
However, in your creation you had the four wedges followed by the wheel right away instead of stacking more pipes or block.
I remember a Swedish youtuber called "Stamsite" accidently creating that in one of his videos, it was a piston powered car challange where he didnt wanna make an engine so he wanted to push the wheels with blocks, and accidently discovered that glitch. I think it was in like 2019 or 2020, just thought id add that if someone has had a similar experience. Also you forgot to test the concave wedges and duct corners.
I think the issue is the fact that the pressure is not being applied at the base anymore, from the first multi wedge test, while more wedges means faster, the pressure needs to be applied at the base, near the bearing
You should have this as a workshop video after about a month to give people time to experiment with this and create crazy contraptions
id like to see this as a race on multiplayer monday lol
After watching this, i have so many ideas about survival base defense after watching this.
I was literally thinking of brick power yesterday!
Using logic gates, you could use this to make a fully manual wedge powered car with 2 gears, reverse, and neutral gears (and technically also park)
I feel like the friction of the block being pushed into the thing you want to spin will affect its speed, so you find a round object that has the lowest friction, then get a mesh block, use a controller to put it diagonally, and push that into the wheel.
Hey dude i just got on Scrap Mechanic and watched this so im gonna try it!
With great power comes great professionalism
Happy holidays to all the item gangs!🎄🎁
So you basically created gears. The more that are engaged, the lower the speed, but higher the torque/power. It also seems to be pretty consistent. I would be interested to see if you did a 4 gear design, if that would have more torque than an engine or two, and be able to move more weight over flat terrain, or uphill. Could basically be a semi for SM.
On your next multiplayer Monday you should do a challenge where you can’t use an engine. This can be your secret weapon. Merry Christmas!
I've messed around using the orange mesh block since it's low friction for this. seems like what direction and angle you're moving at can affect how well it works with those, wedges seem to give a more consistant speed. shame they're almost impossible to get in survival.
Congrats to reaching out for 666k subscribers
and thus begins the wedge revolution
the mumbo of scrapmechanic
Welcome to wedgelogy with Scrapman
you should see if you did the same thing for the first wedge but have them set up in groups of 2. 2 wedges per piston and have that set up on the same side with a switch for each and see if that works like gears and maybe gives you more power.
Now I want to see the trio use cars only using wedge power
18:33 I CANT STOP LAUGHING 😂😂😂😂
Looks professional
It might be worth to test angling blocks and using them as wedges, you could test different friction too
I propose to call this newly found physic as Wedge Force
Wedges are like the probability space ship in A Hitchhiker's Guide to the Galaxy. Idk how fast they gonna go but they will definitely go.
I think that the reason the concrete block test goes *so* fast is the offset of the weight from the center of rotation. If you had had, say, blocks connecting the powered part of the axle to the wheels instead of going straight to the wheel, I think you might encounter a different result than you expect.
This is so much simpler than the other piston powered vehicles made for survival
Just an idea but going with the whole two speed idea maybe there's a correlation between the surface area of the wedges and the amount of torque produced meaning that if you have less wedges touching the pipes the wheel would move faster. It's be cool to have the wedges that are currently connected split up with more pistons pushing them (in say groups of 2 instead of 5) then to start off you would have all of the wedges pushing the pipes then as you increase in speed and need less torque you take away more pistons much like how a torque converter works
the power of the wedge is phenomenal
future experiments: it has fast rpms and low torque, maybe put a lower gearing with some kind of gears fir more torque? different angle of the wedge? more pistons? put the mug/cylinder on a bearing too? add many more of the wedge engines on it and connect them with gears?
Maybe try it with different sized pipes and with wedges from all 4 sides or maybe even from like 45 degree using controler
hello mr. Scrapman, have you considered that the wedge motor might have high power but low torque? that could explain why the wheels on the wall had such a speed, yet when applied to the vehicle it had problems.
Two things
1. Does coming off with wedges from one side like you did on the wall have more power than extending wedges on either side of the piston like you did on the car?
2. I've been meaning to suggest/request for a survival theme a no engine them (gas or electric) like only using piston or controllers to power anything. I think unconventional builds would really force some lateral thinking and creativity.
“With small wedge comes great responsability“ -Spidermans Onkle probably
So I think the reason it’s barely going at the beginning is because it’s not actually contacting it that much so what I think is the prototype is a directly attached to the wall but the car is extended a few blocks out to where the piston is with the wedges so it’s not actually getting all it’s push therefore less power
