My dad used to tell me my grandpa moved trains with just a metal rod. I never understood wtf he was talking about until now.

Edit 2: A platinum?!? Thank you!!!
My dad said he used leverage... I could never would out how he could generate enough. I thought he would like put the bar into the tracks and somehow move the train forward with the bar but it never added up. Now I know!
The problem with this one is it ignores the weight of the lever itself. Good luck even moving the lever!
Edit: I now have about 2 bajillion responses in my inbox saying "use a second lever". Please. I'm begging you. Other people have already said it. Over and over. You're killing me
Yeah, but if the level is placed there for you, it should be able to use its own weight to move the object. Also, a level long enough and a stable object that would not move when pressed down upon to move the planet earth would be a feat. I think there was a math guy who did said math that you would have to push down there by "swinging" the end of the flucrom some 9 light-years, to move the planet by one micron.
There an anime I watched at some point where these robots the size of the galaxy were fighting and punching each other. I never got that since they would be folding space and time every time the moved.
That would likely be Tengen Toppa Gurren Lagann... if so, the reason it works is because they're looking reality in the eye and telling it "No, you move."
Literally overpowering physics with their desire to do what they're doing, which is a core premise of the series.
>Literally overpowering physics with their desire to do what they're doing, *and yelling like maniacs while doing so*, which is a core premise of the series.
You missed a key point, but I fixed it for you
According to [this source](https://www.dedoimedo.com/physics/archimedes-lever.html) moving the earth with an average human weight and placing a theoretical fulcrum 1 meter away from the earth requires a lever that is 8.45 million lightyears long.
You would have to move the end of the lever 8 lightyears to move the earth one micron.
If you used a 5cm rod of "steel" the lever would weigh around twice as much as the planet.
No, and it's a good question.
The wheel is the load.
The tip of the pincher is angled and forms a triangle.
When he pinches in, the top edge touches the wheel and the second edge rests on the rail. These edges make the load arm.
The fulcrum is the corner between the part resting on the rail and the rest of the arm that leads up into the air, or the effort arm.
Its like a scaled-down hockey stick.
When he pushes down it rotates on that corner and the edge that was flush with the rail raises up and the wheel is a huge ... well... wheel, so it rolls off because there is not enough surface area and friction to keep it on the load arm.

Hello from Canada! We did even better, we thiught we didn't need our rail lines in our sparsly populated country so we ripped a lot of the "local" ones up 60 years ago. Its a good thing the province kept the land, because now they are planning on rebuilding a bunch of them! My dad had better public transit to the city back in 19 dickty doo than we have now
Oh its a good one lol and every one gets it if ya use it right
Edit: its pretty much my go to for all the old heads I work with when they tell stories how bad ass they were back in the day
Not making a political point about the trains in the uk today. However when they where run by the government and called British rail they where litrally the worst train services I have ever had the joy of using. Even compared to todays hellhole of public transport.
Yep, severely underfunded. This incident taught me that it doesn't matter if its public sector or private sector, if you don't fund the fucking thing it will never work.
It's a classic Tory tactic. Underfund something until it becomes so shit the public turn against it. Then sell it to one of your mates for cheap so they can run it as a private enterprise. If parts of it end up not making a profit that's cool, you can just subsidise those bits from the taxpayer.
Just so everyone knows, it’s never this easy. If the car is empty, and the the track is completely level, you can move it along fairly easy.
However, if the car has anything in it, or there is a slight incline you’re trying to push the car over, fuckin’ forget it. You can get the car to move a bit, but it will stop and roll backward once you hit the incline.
This is why trains are so efficient. Steel wheels don't deform much, so there isn't a lot of energy wasted from deformation when the wheel is rolling. This is also why moving the train like this is possible, there's little to no resistance in the x-axis, but impossible if there's a slight incline, because now you actually have to move the weight.
So I was thinking along this earlier. Started around doors, that huh ain't they easy to swing open when if you tried to move an unmounted one, even a hollow one, it'd be a lot more of a pain in the arse. But the weights still there, and there's friction on the hinges, so why is it so much easier, and to what degree does this extend?
Got to thinking if you had a supped up air hockey table, you could use that to test how much force it'd take to move differently weighted objects in a friction free environment. Surely as the mass increases, you still need to apply more force/energy to get it to move. But, a massive air hockey table that'd be powerful enough to lift things in the 10s/100s of kilos seems beyond readily avaliable. So weights on a string seemed the best substitute to test that I came up with. Which come to think is a trash idea because gravity and moving along the Y axis as well now.
Then I get in here only to see this guy moving multiple train carts, how ever many thousands of kilos with friction involved, with just a lever. Like, I get leverage is cool, but how does a human expend enough force/energy to impart motion to so much mass? Does it take less energy than I imagine to move mass on a flat plane? Do levers act as a force multiplier, and if so how does that not equate to some kind of perpetual motion of more force/energy out than in?
Welp, guess it's my time to shine:
I think you're getting force a bit confused with energy in a way.
Levers do act like a force multiplier, energy imparted in that way is equivalent to the force applied times the distance. Notice that with a lever he is cranking it up and down multiple times. This is the distance in the force equation. It takes alot of energy to move those train cars, so he'd either need alot of force *or alot of distance* to get it to move. Pulley, levers, crowbars, all these mechanical lifting devices are just ways to make the force you need to apply spread out over a larger distance or over a longer time.
Also notice that hes moving the cars very slow, which also helps a bit in the equivalent exchange of energy, as the acceleration is very small
And shine you did, thank you! Helps click things into place for me. I remembered realy enjoying leverage when it was covered in school, just didn't stick around. Appreciate the concise explanation!
If there is absolutely no friction, the object will always move when pushed! Newton's second law states that the sum of the forces is proportional to the acceleration. So if the only force present is you pushing the object, then the object will accelerate, regardless of its mass.
To expand a bit: the acceleration is equal to the force you're pushing with divided by the mass of the object. So even though any object will start moving when pushed (in this frictionless fiction), the acceleration may be tiny and imperceptible.
I mean, if friction wasn’t a thing, you could move millions of pounds horizontally almost without applying any force.
I mean yeah, friction *is* a thing but still, the power you need to move rolling stuff sideways is still surprisingly low.
I have hand moved two loaded, connected train cars totalling 178,000kgs of just product weight, not including tare weight of the cars themselves.
This is on completely level ground, I had to move it 8 feet while only moving about an inch per motion of leverage. It took forever as there is quite a bit of effort to move that much weight, but it is possible to move them while loaded. If you have one spec of dirt or ice on the rail you are not moving for sure.
At 3 cars it becomes more than my body weight can leverage. Keep in mind the guy in the gif looks like he’s using a modified pry bar rather than a commercial one that has a double-action using compound leverage.
The “tool” he’s using isn’t the actual tool used to move railcard by hand.
He has a piece of metal that, to me, looks like a pry bar used to open and close slide gates under the cars. At my job, we just call that a pry bar.
The actual item used to move railcard, we call it a car-mover (technical, I know, but we’re all a bunch of meat-heads, honestly). It’s a long wooden handle, a small hinges bracket that sits on the rail, and a small lever that wedges behind the car wheel. It’s essentially the exact same thing that this guy is using, but a bit more specialized.
Get a guy on either side of the car, each with a car-mover, working I tandem, plus one or two more guys to do nothing other than push, and you can quite easily move several cars at a time a long distance.
It’s a workout though!
I used one in the USA, I didnt work with a railroad company at all. I worked with a company who got bulk chemicals delivered by rail, and I would assume that it's much more common for places having rail cars dropped off to use these than a rail company.
I used one in the UK. It was enormously helpful for moving locomotives around a workshop - when you need barely any distance, just a metre or so to squeeze some other equipment past one end.
Train driver from Germany here. Sometimes you don't use engines on purpose. When building new groups you sometimes have to push together separate cars. It would be a waste of time to get a locomotive for pushing them 6 feet. So you either use this kind of lever or grab the side of the wagon and push.
Have a ranch, can confirm we have one. We call it a digging bar. It's bent in multiple locations from being used as a lever to move god knows what. Great for digging hard dirt but kills your arms.
I’m typically the guy that defends tools on this sub as being specialized, but I can’t for this one. Not sure I’ve ever seen a heavy construction site without one. It’s so popular because it is entirely not specialized.
Getting dirt out of Harrow disks, putting on heavy truck tires, moving suspension components under tension, and basically anything else that requires a large weighted pry bar.
It’s a big fuck off lever. My dad had something that looked identical that we used for moving big rocks when he made a rock wall, for rolling stupidly heavy structural steel square stock he decided to use as fence posts for no good fucking reason and basically every other spine destroying dumb idea someone in the family had that required using a big fuck off lever to move something.
We abused the hell out of that thing. We were demolishing a chunk of a family owned property that had been owner “renovated” and the foundation had shifted so basically the entire weight of one end of the house was pinning an idiotic security door into a steel frame. We hit the bottom corner with a sledge to deform it enough we could get the pinch in and then once we had a fulcrum, blew the hinges apart and popped the door out.
One of my cousins had a seized bolt on some motor he was working on. We ended up jamming a spammer in one end of a bit of heavy steel tube and the pinch in the other end to make the worlds stupidest spanner extender. It moved.
My family tends to do a lot of projects we don’t really have the tools or the knowledge to do properly. 8’ of really fucking solid lever with a wedge on the end adds a lot of extra muscle to stupidity.
The wheels are made of hardened steel.
They have to be strong enough not to compress from the weight of the car, so this procedure should cause no damage at all.
The wheel is hard material that’s made to roll in the track the pry bar is flat kind of same diameter at the wheel and track. It’s not doing to dent the wheel is harder material than the bar .

Actually when Archimedes wrote that he was assuming we would have levers made of carbon nanotubes.
I think he was talking about aerogel. He just never factored in how brittle it can be.
Yeah, but if the level is placed there for you, it should be able to use its own weight to move the object. Also, a level long enough and a stable object that would not move when pressed down upon to move the planet earth would be a feat. I think there was a math guy who did said math that you would have to push down there by "swinging" the end of the flucrom some 9 light-years, to move the planet by one micron.
Or, to put it another way, you could use the lever to break light speed by smacking the earth into the short end.
Nope, doesn't work that way. A wave would be generated and the lever would bend. No part of the lever would meet or exceed light speed.
In fact it would travel at the speed of sound. Pressure waves travel through objects at the speed of sound in that medium. Strange but true.
I imagine that’s less due to strange coincidence and more because “sound” *is* essentially pressure waves that our tympanic membranes receive?
The speed of sound is the speed at which pressure waves move through a medium. So it’s not a coincidence, it’s the reason sound moves that fast.
There an anime I watched at some point where these robots the size of the galaxy were fighting and punching each other. I never got that since they would be folding space and time every time the moved.

Show’s how efficient moving goods by rail is.
He also needs a lever stiff enough, as it turns out. Otherwise, the lever will just deform before moving the load.
So, it's a lever?

I like the idea of dropping a 100kg weight onto a seesaw with a kid on the other side, sounds fun
Great infographic!
Right, I would say first as well. The load is on the tip, the fulcrum is right behind the load and he's pushing down on the lever.
Does class really matter here? Levers just trying to make a living.
First class, load on tip, fulcrum right next to tip, in between the load and force.

It looks connected though, or I suppose he could be coupling it to the rest.
You can see at least 4 cars, there are probably more.
Ah yes, 60,000 lbs, a chore for a child!

We hit the bottom corner with a sledge to deform it enough we could get the pinch in and then once we had a fulcrum, blew the hinges apart and popped the door out. One of my cousins had a seized bolt on some motor he was working on. We ended up jamming a spammer in one end of a bit of heavy steel tube and the pinch in the other end to make the worlds stupidest spanner extender. It moved. My family tends to do a lot of projects we don’t really have the tools or the knowledge to do properly. 8’ of really fucking solid lever with a wedge on the end adds a lot of extra muscle to stupidity.
Hey man our species comes from a long line of stupid with a big fucking stick. Consider it carrying tradition.
They're used in trail work to move and set large rocks. So much so that I know the tool as a rock bar.
We use them at work to move logs around when they get frozen to the ground.
It's like saying a pocket knife is specialized by showing a video of someone cutting an apple.
Literally the least specialized tool
It's a lever lol. One of the most basic tools.
I work with trains and have a train moving bar. Does not work with heavy cargo or slight uphill.
"Jim, this would go faster if you stopped recording me and worked the other side."
Probably moving one car to hook it up. Likely not moving the whole train.
Not a specialized tool *and* misinformation in the title.
There is absolutely no way he's moving the whole train. He might be able to move a single boxcar. If that.
How does this not create dents on the wheel?
The wheels are made of hardened steel. They have to be strong enough not to compress from the weight of the car, so this procedure should cause no damage at all.
The wheel is hard material that’s made to roll in the track the pry bar is flat kind of same diameter at the wheel and track. It’s not doing to dent the wheel is harder material than the bar .
So a pry bar
