Archimedes' screw - Working model

  • Earlier, we looked at key terms like pitch and thread of the screw. Archimedes applied the principle of screw to help farmers lift and move water from river to fields. Today, this screw is also used for movement of grains, slurry and other industrial products. Instead of water, we will use grain to understand its working. Screw is built from a card sheet and casing from a thick plastic sheet. How to build this screw we will see later.
    Just like the movement of the steel ball we saw earlier, we will place a steel ball and rotate the screw, it comes up all the way. Let us add some grain to the glass bowl. As I rotate the screw, grain moves up. Empty space is taken up by grains in the container. This process continues. Screw is responsible for this movement.
    Circles are cut from the card sheet and cut into rings. Paper pipe forms an axle around which each ring is glued incrementally. With every rotation, it carries a small amount of grains upward. This is the basic principle of archimedes screw. This A4 card sheet is wrapped around our paper screw, so that a sealed casing is formed. A small cut near one is made for grain to enter the enclosed screw.
    Screw can be constructed with this large PVC pipe as well. It is cut in half for some part. Paper rings are wrapped around smaller PVC pipe to form a screw. Material exits the screw from this opening. If we place steel balls here, after some time, these will come out through the opening.
    Let us move some grain with this screw.
    Same screw design is used as well to lift water. I could not do it as this arrangement is not perfect and has lots of gaps through which water drains down easily.
    I will have to think of some other method for lifting water.
    In the last video, I wrongly mentioned this setup as an Archimedes screw. Actually it is a coil pump which looks similar to an Archimedes screw but works on different principle. I will discuss the coil pump in the next video.
    Do try these variations to know more about archimedes screw.
    .
    Thank You.

    Wow sir!! It's really good for us, to understand the principle of Archimedes' Screw...
    Really!! The creation of Archimedes is just impeccable....

    Technically Archimedes stole the idea from nature. Conical sea shells with the end broken off or a hole inside were the first ones and where the effect was noticed. Simple playing around at the ocean etc would reveal this to whoever noticed it.................then it was replicated in scale, length etc

      There's no evidence that he stole the idea, nor evidence that he even claimed to have made the screw, nor even evidence he ever applied it himself. Older texts reference the screw as something he found in Egypt. He was only described as the inventor hundreds of years later, likely due to his fascination with spirals and likely to make a local "hero" out of him. That's the gist of it, if your interested in knowing more, there's a book by Dr. Stephanie Dalley, an Assyriologist, called 'Mystery of the Hanging Garden of Babylon,' in which she spends a decent amount of time talking about the Archimedes screw because she has compelling reasons for believing it was a significant method by which water was moved.

    Wrong construction, energy inefficient.
    Much less energy is needed if you remove the friction with the tube that happens all the way along the inner screw
    The outer tube should be fixed permanently to the inner screw closing the spiral chamber completely.
    Then the top and bottom of the whole thing should hang on bearings and the rest of the device should not be in contact with the surrounding.
