How Levers, Pulleys and Gears Work

[@TheEfficientEngineer]

Thanks for watching! Let me know what you’d like to see next in the comments. And don’t forget you can watch the bonus video on Hydraulic Systems over on Nebula - nebula.tv/videos/the-efficient-engineer-understanding-hydraulic-systems.

[@SirprofMagic]

Thanks once again. A video on how things like pumps, dams, weirs and water treatment plant plant works will be equally great. Your work is really helping.

[@physicslover1950]

I would like to see a never before seen video on enthalpy... Why we always use enthalpy in majority of our thermodynamic calculations and formulas? How enthalpy is different in liquids solids and gases...? Enthalpy is a very very confusing topic in thermodynamics... The formula that Enthalpy = Heat ( Thermal Energy) + PV ( pressure volume product) is actually super confusing for most of us (thermodynamics students) all the teachers have failed to explain this concept especially when this concept is applied in Joule-Thomson Expansion .... Websites , books, teachers and even the Professors say that Joule Thomson effect is an isenthalpic process.. However they really fail to properly and intuitively explain this... the confusion arises form the fact that a sudden compression or a sudden expansion is always refered to as an adiabetic process before one reads the Joule-Thompson Effect ... They say, " Joule Thomson Effect is not isentropic (reversible adiabetic) or adiabetic though there is a sudden expansion; it is an isenthalpic process" Another confusion arises from the fact that isothermal compression and isothermal expansion is always isenthalpic.... Because as soon as the pressure increases it will dissipate heat and as soon as the pressure decreases it will absorb heat from the surrounding ... But if we look at the Joule Thomson effect it is not isothermal the temperature drops and most unfortunately what ruins everything is that sometimes temperature increases as a result of sudden expansion 😵 ..... So we still can't apply the adiabetic logic here because according to adiabetic principle gases cool on expansion while gases are also weirdly heating up on expansion.... Why is this so.... ? Can you please explain what happens at the molecular level? ( animations or simulation on microscopic scale )

[@DrZygote214]

I request Bearings, Seals, and Valves. Very important to know how those work and how they wear down, and what sort of abuse wears them down quicker. For example an unbalanced rotating mass can damage the bearings.

And here I am watching it to understand how my windlass, bowroller and anchor + chain all interact and trying to maximize my windlasses ability to lift my anchor 😂 If anyone is bored and wants to help. I have 250' of 5/16 chain, 70lb anchor, 1.5" bowroller and the windlasses low point is 3' back from the high point of the bowroller... so how high or low from the top of the roller 😂😂

I wish videos like this existed when I was in college. We had KZbin, but it was the early days of it and mostly just people doing stupid things. It also took an hour to load a 5 minute video! I'm enjoying relearning the basics recently, so much of this stuff quickly gets forgotten after the exams if it's not regularly used!

[@justadude8716]

I was confused by pulleys and how they work and your video made everything clear to me!

[@martyjoseph9507]

One of the best explanations I've ever seen, covering many questions at once

[@josephlai9759]

Thank you for sharing. The animation is so wonderfully done. It made understanding the subject so much easier. And the logical progression of explaining from lever to pulley to gears is extremely clever and well thought out. This must have required a lot of imagination and fore thought.

[@francoisl7663]

It's been so many year's since I've graduated. Your videos are so helpful to refresh high level conceptual concepts. Thanks

[@mgh-channel]

This is now the best channel that I have watched in KZbin in terms of explaining engineering concepts and clear animations. I've almost watched all the videos in this channel. Thanks and keep it coming.

[@stephaniehitchcock]

This helped me so much, I am currently studying for technology and when it came to pulleys the teacher’s stuff was so vague and didn’t even explain it. Now I know it so well. 👏🏼👏🏼👏🏼👏🏼👏🏼

[@andreabianchini53]

After watching this video I suggest to take also a look to the Chevrolet videos about spinning levers and differential and the circle is finally complete!

[@JCtheMusicMan_]

A gear can also be seen as a wheel of levers where the moment is at the center of the gear and each tooth is it’s own lever. Great video! ❤

[@Dontexxr]

That is very true thanks for that.

[@ScienceDiscoverer]

Yea, I was always imagining them this way too. Imagine that each tooth is a lever with both sides of it equal to each other, but 2nd lever is shorter. And you act with one lever on another.

Thank you for making feel less stupid. I never understood when my lecturer tried to explain it. But now it's clear to me.

[@EugeneSorokacorp]

I'm an EE. Im fascinated by mechanical systems but dont know much about the details. A lot of this stuff is somehow very intuitive, but the reasons why it works seems like magic. Your explanations of the reasons why it works are excellent and easy to understand. Subscribed. Looking forward to more videos! Also i keep noticing how almost all mechanical systems have electrical equivalents with similar equations. The hook's law spring with a mass differential equations are very similar to capacitor and inductor differential equations for example. Gears are similar to electrical transformers. Pulleys and levers are like electrical amplifiers. Its pretty neat how that works out.

[@dmaster20ify]

I did an experiment and found that the weight of the lever is important if the weight of the items being placed on it is not heavy enough. Also, the tensile strength of the lever is very important if it is to lift the object.

[@The_Green_Man_OAP]

2:00 _Levers are the basis of everything._ Explain them and you can explain all phenomena. Note that the beam must be under tension for the applied force to be transmitted along it, via _transverse restoring forces_ over a time interval, aka _impulse waves_ . If the situation was _static_ ,the waves would interfere and you'd get a _standing wave_ . If it isn't tense somewhere (like the pivot), either there's no load or the beam has snapped!

[@TheophilusTheThird]

3 colleagues and I from MIT proved that the pyramids could've been built using mechanical advantage accomplished with wooden gears, levers, and pulley systems. All using wood, stone (including stone bearings), and levers, we were able to hoist 47 (that is all we could source for the research) blocks, each weighing between 2 and 2.7 tons. They were hoisted 75 feet into the air, and pivoted out 32.5 feet. We were able to do this in a footprint only 22 ft x 16ft, using only 5 guys. And did so within 6 hours. We proved that the system was mobile, able to work on top of itself, was able to be made sourcing ONLY materials available 6,000 years ago. We believe we could build the pyramids. BUT we dont know how the cuts were made, how they transported the stones from hundred of miles away, AND there is no proof or reference of these kinds of systems being used back then (although the math and understanding of these concepts were known individually - but not sure if they were ever combined in any application). This would be the same tech that could've built Machu Pichu, and various other megalithic structures in antiquity. We are currently sourcing funding to see if we can EXECUTE this concept by building a 1/5 scale model of the Great Pyramid (we would basically just build the top 1/5 as a proof). If you can build the top (where it narrows the most and requires the most intricate approaches), then it would be ABSOLUTELY possible to build the bottom applying the same principles. When we finish - we will release everything (videos, schematics, and designs) for others to research.

if we can use less force to lift something with a lever that we would normally, than how is this NOT a perpetum mobile? Why can't we lift 1000 liters of water 10 meters higher with just a liter of water from the height of 10 meters and than use 1 liter out of these 1000 liters of water to get it up again after we use that high up water to power our turbine?
