    Snatch Block!
    I want to take a moment to thank those of you who support Smarter Every Day on Patreon. I'd also like to point out 2 things about this video.
    #1. You'll notice Jeremy Fielding is in this video. He's the "Contraption Fabricator" that's started working with me now because of your support on Patreon. He's a great designer, father, and friend. You'll be seeing more of Jeremy around thanks to those who support at www.patreon.com/smartereveryday/
    #2. If you'd like to 3D print the Snatch Blocks and pulleys we use in this video they are here: www.thingiverse.com/thing:4022579
    #3. I really enjoy KiwiCo and I think you will too. I got them as a Christmas gift for my children years ago, and it was a huge hit. It was after that experience that I reached out to their team and asked if I could advertise for them because of how good it was for our family. I think you'll enjoy it too. www.kiwico.com/smarter
    It was 3 things... I ended up pointing out 3 things.

      @melanieenmats you are right. Gears and pulleys are just more sophisticated levers. And with lever you lose distance but you gain force.

    Work is equal to the force applied, multiplied by the distance across which it is applied. W=F×d
    By the work kinetic energy theorem, the work done on the system is equal to it's change in kinetic energy. W=∆KE
    In a conservative system, for a component that itself does not lose or gain kinetic energy, the work done on that component is equal to the work done by that component. W_in=W_out
    If the component is moving a different distance at one end that on the other, then the force associated will be different, since the work is the same. F_in×d_in=W_in=W_out=F_out×d_out
    This means the output force is equal to the input force, times the ratio of distances. F_out=F_in×(d_in/d_out)
    It is this ratio of distance that is the mechanical advantage. MA=d_in/d_out
    This is how mechanical advantage works for any system: pulley, lever, gears, etc.

      The calculation requires distance, which means the things have to be moving... but what about things that are balanced, like hanging weights in a pulley system. This one's a tad more complicated mathematically, but it basically works out the same way.
      In a conservative system, the potential energy function is equal in magnitude to the work function, with respect to some defined zero energy position. Assume the mechanical components, like the rope and pulleys, doesn't add or subtract energy from the system (ignore miniscule amounts of stretching and friction). Each side of the system (input and output) has an associated potential function.
      A system will reach equilibrium when the total potential energy of the system is minimized. Since the potential energy functions are based on the work functions here, the balance point of the system will be based on the ratio of distances from the zero potential points, and the ratio of supported weights which balance is the same as the mechanical advantage.

    What would happen if you, instead of tying off the rope to the hook on the way right, you extended that rope with another pulley, and brought it over to the left side where you pulled on that rope, as well as the rope youre already holding????
