    Finally the first video to explain this well

    If you can't tie a knot......tie alot.

    Also explain how it distribute the weight on 2 lines, so you can pull almost double the weight

    Thanks for the instructional video! It works exactly as it is needed to do.

    How are you anchoring your top pulley?.. when you're using the anchor hole as a Beckett?

    Dang it bro. I was misled. I used your system as a guide while at Home Depot but I now see the anchoring issue other commenters are mentioning. Oh well. Lesson learned! 😂

    Your top pulley is upside down.
    It needs to be attached to an anchor point for this sinario.

    Give us an example of you lifting something using those two particular pulleys and the same configuration.
    My prediction is you won't be able to because your top pulley is upside down.

      and the rope is rubbing against the top pulley

      I believe he was just going for modeled concept description. In that case, it doesn't matter if it's practical. Or does ittttt......?

    I am always thinking, is it possible to lift an elephant with a single finger, by utilising 1000 pullies? Today after watching this video, I am confident to say yes, but I have to pull a distance of about 1000 metre to lift up the elephant to just 1 metre height.
    As according to the conservation of energy, the equation can be written as:
    Work by Finger= Work on Elephant
    Finger Force x Finger distance = Elephant Weight x Elephant distance.
    If inputs are:
    Finger Force= 40N
    Elephant Weight= 40kN
    Elephants distance= 1m
    Then outpu will be:
    Finger distance= 1000m

    In theory it works but in practicality there is nothing to attach the top pulley to.

    How you supposed to suspend or hang the too pulley

    Hi I’m interested in this type of pulley, but I want to be able to lock the system when the weight is up. I’m planning on using it for a heavy bag for boxing that I can easily attach and detach since I’ll be using it outside. Do you have any tips?

    How do I alleviate the pressure on pully one if it is connected to a weak tree to pull a big shed ? I have to pull it from the direction of the video shown due to space crunch. I have a big tree to tie on to the left if that helps

    How do I design a system and size the pulleys, rope, etc , if the only info I have is the weight of the object I want to pull

    How much are they???

  • @mentalmoto763
    @mentalmoto763 ปีที่แล้ว

    its only a single by the way. the upper pulley is for angle change only, no advantage.

    • @petecassidy1513
      @petecassidy1513 ปีที่แล้ว

      Nope. Just made one and the pull required is a little more than half to lift the same load. This system works as it should.

    • @mentalmoto763
      @mentalmoto763 ปีที่แล้ว +2

      ​@@petecassidy1513you didnt read what i said, the pulley he holding in his hand has no advantage.

    • @koda7820
      @koda7820 10 หลายเดือนก่อน

      Nah you’re pulling half the weight the way he has it set up

    • @mentalmoto763
      @mentalmoto763 10 หลายเดือนก่อน +1

      @koda7820 the lower pulley is creating the mechanical advantage, the upper is for angle change only

      He was going for proof of concept, not practicality.

    Not how that works bubbu

  • @rebeccachambers4701
    @rebeccachambers4701 หลายเดือนก่อน

    So since you would have to pull it twice the distance. Then I am assuming the amount of weight does not matter really in relation to that distance so essentially if I want to only have to pull, let's say about 2 feet. Then the total rope would only have to be under 2 feet. Not to mention with the compounding pulleys I'm just ordered police and I'm just gonna try to experiment. See if I can figure it out without it. You can get confusing

    Excellent description of the concept and action. Thankfully without any distracting music. Thank you!

    My only comment is that you should never "tie off" cordage directly to sharp edged hardware. Caribiner be used as transithion.
