Excellent. I really like the way you include the (very accurate) distance measurements, showing the travel of the input and of the weight. That really helps to drive it home, sts. Nice demonstration! Anyone watching should note the EASE with which you pulled the input down 5 feet.
Yes. This is the way to build a working lift and move one rope with pulleys system that I was trying to picture in my head in the earlier video comments. Just like in the video thumbnail, everything has to be in sideways and not between the weight and middle travelling pulley. So you just hook this system to the middle travelling pulley and the other end between two trees with pulleys, through the middle travelling pulley and back and down to load through carabiner(for friction to keep the once lifted load up) that is connected to the travelling middle pulley and boom you have a working concept! Self raising and tensioning rotating double rope line that can lift heavy objects with good mechanical advantage and can move the loads in both directions. Thank you!
@@perryfire3006 I bought the necessary equipment and tested this myself and its working okay. Just a warning to everybody if they are going to build this. If the load gets stuck somewhere and cannot move sideways and the whole system can't rotate, the angle of the ropeline is reaching 180 degrees and the tension to both tree pulleys is theoretically reaching infinity if you keep applying the pulling force. So make sure the connection between the tree and the tree pulley is atleast 10 times stronger than the breaking force of the rope in the system. If if the connection between the tree and the tree pulley fails first, the pulley is going to fly very fast and can easily even kill someone.
Great video. Though you really should have weighed the weight with the scale directly, before weighing it indirectly. Especially considering the effort you put in to try to prove this over all.
@@perryfire3006 Nah, you did great. In fact, you did so well, I was little let down that you didn't quite do it perfectly. But yes, I think you proved your point quite well.
I need to rethink how I shoot these videos. Nobody wants to be on a boat trying to figure out what I am talking about. Thanks for the input and thanks for suffering through my content. Cheers
If you had not tied the first pulley to the rope, but instead hooked it to the a common anchor with the third pulley, would that have been a 3 to 1 system?
You count strands in simple systems. That is why it is important to know the T method for complex systems. Also, you can use the T method for double-checking your assumptions in simple systems. Cheers

Thanks so much for the comments. The encouragement is motivating!

Yeah, its imperfect. I think it was close enough to validate my assertion for me but your point is taken.

Mate great content, but I have sea sickness form the constant moving camera. maybe a stationary tripod?

@@perryfire3006 🤢 Mate good work taking the time. It's appreciated. Always learning.
If you had not tied the first pulley to the rope, but instead hooked it to the a common anchor with the third pulley, would that have been a 3 to 1 system?
Yes! It would have been a 3:1 with a COD (change of direction) pulley at the anchor. Good eye for details.
You didn’t account for the weight of the rope and the hardware hanging from it.
I didn't, nor the friction. The test was imperfect for sure but I still think it proves my point. Thanks for watching.
I thought you counted moving strands.. In a complex system like this you have more than one moving block.

Proof is in the pudding!
Glad you liked it. Thanks for watching!
Awesome
Thanks so much
I just wanted to see the system work! ugh...

Not the exact system but it showcases mechanical advantage with pulleys.
