      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?

    I wish videos like this existed when I was in college. We had RUclips, 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 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.

    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!

    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.

    I'd like to see a video on sizing pneumatic rams, and how to work out the best place to position them, and the forces involved.

    I need one clarification. In Pulley concept , only pulling force will reduce based on number of pulley.
    But if all top pulley fixed on the steel beam, then that beam experience the equal force which is loaded. Right.
    Ex. 100 N

    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?
    Edit: nvm turns out you're explaining it later on, great video.
