How Levers, Pulleys and Gears Work

Watch the bonus video on hydraulic systems here: nebula.tv/videos/the-efficien...
⚙️ This video explores different methods that can be use to amplify a force, and focuses on three types of machine - levers, pulleys and gears. The amplification of a force is called mechanical advantage, and it is useful for a wide range of applications, like lifting heavy loads.

    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 )
