[@TigersLullaby125]

Don't forget the most important part. 1 way valves! Same way every form of pump works. bicicle tire pumps, pumpingwater from a well dug deep underground, vacuums, siphoning your neighbors gas out their car, hydraulics, pressurizing and depressurizing things (Which is used in all cooling systems like your freezer/air conditioning or making liquid nitrogen since the only 2 methods possible to cool something are 1. Introduce it to a colder object that steals heat, or 2. Depressurize it) 1 way valves are key to soooo many things but it's so basic that it gets underestimated. It's literally just a flap that opens one way but stops the other, like your front door probly has the frame stopping it from going the other way. It's why when you push a bikepump down you can shoot air into a tire but when you pull it back up you're notjust cancelling that work sucking the pressure back out because 1 valve faces into the hose to be the only output of the air while the other valve st the bottom of the pump piston makes the only entrance for air. So with 1 way valves the air can only enter from outside andcan only leave through the hose. Those valves allow it to move only 1 direction and allow buildup of pressure which can turn into some of the strongest forces generated by mechanical means. I'm sure we've all seen some videos of crushing things in a hydraulic compressor or engines using the same thing to power cars and lift physical Tons of weight with cranes. Every engine uses pressure and that requires 1 way valves. (Although the force to push those valves is chemical combustion rather than mechanical) Just as cool as torque/leverage (Which are the same thing, big gear to small gear ratio/big pulley to small pulley wheel/length of lever arm from fulcrum multiplied by perpedicular force are all the same thing) You could literally build a crane capable of lifting your car just using trunks of trees as "wheels" making a pulley that multiplies force and then just pull the rope a little and suddenly our weak human body can lift a car no problem lol. Leverage theorhetically has no limit also as long as the arm itself is strong enough to withstand not breaking or bending, the longer the arm the greater your input force is multiplied at the fulcrum. Which is why when removing tires you have to use that long @ss lug wrench, torque force = arm length X applied force. Otherwise those nuts would be wayyyy too tight for a human to loosen with a small wrench. It's really crazy when you think about how just a few basic principles make up like 99% of mechanical things. If you knoe the basics you can apply to see how just about everything mechanical works. Even the transmission of a car is just a fancy gear box changing the gear ratio which converts torque to rotation speed or vice versa the same way a bike does when you change gear the chain just gets pushed onto a different sized gear making the pedals harder or easier to push. Like EVERYTHING works with just a handful of the same basic mechanical principles👍🏻😎

[@TigersLullaby125]

Bad habit I type too much😂 I'm a physics guy just camehere cus my caveman instincts wanted to see the bottle jack haha. My mind was wandering but I was originally theorizing about using leverage by building 16 extremely tall and dense poles around earth's equator and then putting rocket thrusters at the tops of each with enough fuel to keep thrust for awhile and see if we can speed up or slow down earth's rotation on it's axis😂 Since earth is slowing down due to meteors and it's not at exactly 24 hours which fcks with me lmao. Eventually it could be a method to help terraform other planets like if we get a much more massive planet to rotate a lot faster then we effectively can lower the gravity by the countering centrifical force as we have here on earth standing at the equator you weigh less than you would standing in new york Doing calculations now I just got distracted. Gimme some cr@ck and a couple days guys lemme cook I'mma do something cool asf or end the world💯

I just got a bottle jack for the first time, and watching this video was paramount to understand the functionality and safe operation of the bottle jack. Job well done!

[@alian714]

This is an awesome explanation for how hydraulic jacks work! something that I'd like to add though is that at 5:22 the bigger piston of the jack doesn't just move a third of the distance of the smaller piston because it needs to conserve energy, it moves a third of the distance because physically more fluid is required to fill up the larger cross section. The law of conservation of energy is always a consequence, never a cause for something!

[@OGRH]

It's funny how the law is obeyed and isn't just a rule but makes perfect sense!

[@Ali-v6g9b]

Can't stop thinking about what you said in the last sentence... 🤔

[@ChaosNe0]

A very educational video which I think should be used in schools to teach mechanical principles. I had watched it with a friend who answered the last of my lingering questions about a topic I had never thought about beforehand. Please make more of these meticulously crafted animations with explanations!

[@jvshore7528]

You are an excellent educator. The tempo of your explanation, the order in which information was shared, and your choice of words made this very easy to understand.

[@palco22]

Most of us have a good idea of how the bottle jack works (... as does the floor jack) but these videos shows the details and that's always interesting.

This video has made me subscribe to your channel. Not only did you explain how it works but also described the different principles behind it. Awesome!

[@Se7nDust]

I tried using a bottle jack horizontally recently, and was shocked when it didn't work...i guess my check valve is gravity seated 🤦‍♂️

[@DavidM2002]

I just bought a motorcycle lift with a hydraulic ram that had a small fluid leak. This video took all of the guessing out of its workings and repair. Well done and thank you very much.

[@ChalonPatton]

Excellent illustration.

[@rugbyguy1rugby407]

This is the best explanation I have seen on this topic.

[@vman2kay]

This explains why you need to have the release valve stem loosened before you uses it (at least in my manual), because if you don't then the oil can't bypass the safety spring if the load is too much and can explode. Nice video!

[@jenbea4753]

Wow, what a great video and explanation of how a bottle jack works. I have to repair a bottle jack on my J & S jack (company now out of business). The hint was to reverse the pressure relief valve gasket. From this video I learned the inner workings of the jack and can see how to reverse the gasket. Thanks so much.

[@edwardsimmons3721]

I really enjoyed this explanation. The details are spot on and explain how fluid pressure multiplication is achieved.

[@mhick3333]

Great presentation

[@RealJonDoe]

This video is absolutely spectacular, thank you for that, I suspect it will help me in my repair of a pallet jack. I have one criticism to make. The type of screw adjust saddle on this particular build is used to extend the jack beyond the typical hydraulic limits, rather than to fine tune the height. There are some made to fine tune, but they typically have another rotator on the top to allow it to be raised while already under load, a near impossibility with this model. If nothing else, the screw top goes that little way toward making sure someone is not using blocks on the top to get a bit more height in an unsafe manner.

[@_BAD_MERC_]

I took all four wheels off my car in April and noticed the jack ran out of ooomph before reaching the top. No problem - added some jack specific oil and it never worked again. I still haven't spent appreciable time trying to see why - but I should. GREAT video!!!!

[@Ali-v6g9b]

When I disassembled my jack I noticed one detail which is missed here: There's a hole in the upper part of the main cylinder, which allows the inside air pocket to move freely between this space and the reservoir's. Its second function is to prevent the piston from popping-out (in case of oil overfilling).

[@نگهداریاستخر]

That was excellant!

[@HypherNet]

Great work and congrats on the new channel (and a new sub!) I love this sort of explanation, and I've always wanted to see a good diagram of how this works. My only critique would be in explaining how pascals law works to increase force from the handle piston to the load piston. I think it would be clearer to just explain what's going on in simple terms and then talk about pascals law, I found it hard to follow. From my point of view: since the load piston is larger than the pump piston, pumping 1 unit of fluid from pump to load will raise it up less far, by the ratio of the surface areas. But because it's going less far, it must have greater force. Since the cross section area is proportional to the square of the radius, you get quite a bit of mechanical advantage for a small increase in radius. Some example of common numbers of force multiplication would have been cool to see, too: "In a typical jack, the handle ratio is about 10 to one, and the area 20 to one, so a 200x increase in force" or whatever. In any case, I look forward to your next video, if you choose to make more!

My bottle jack also has a small bleed orifice hole in the side of the main cylinder just below the mechanical top end stop so that if you raise it all the way up the oil just sprays back into the reservoir preventing you from jacking against the end stop itself. The piston/ram stops lifting a few mm below the stop instead. I call it the lift limiter.

[@pedroasandoval2579]

idk if its been implemented yet but you could make some money of this idea

[@danielthechskid]

@@pedroasandoval2579 ? I didn't add this hole it came stock, it's a 2 ton rated jack that I bought years ago at an Aldi Foods store, IE the US branch of Aldi Süd.
