| Apr 30, 2019 at 22:45 | comment | added | noedne | @PeregrineRook Hm, thanks for the feedback; maybe if I remember later. When you pull one rope, the only parts of the rope that are taut are the half you are pulling and the part connected to the box on the other side of the pulley. Together these move as in a normal pulley system. | |

| Apr 26, 2019 at 13:14 | comment | added | noedne | @HansJanssen Interesting idea! The question does not seem to specify whether the other end is being held taut, so I have not made that assumption, but that is certainly a possibility. Although, it does feel like it would be cheating a bit given that the non-pulling arm would still be exerting a force. | |
| Apr 26, 2019 at 13:08 | comment | added | user29705 | The untouched rope exerts that same tension, assuming it is connected to the ceiling (which explains why it is going up in the left picture in the question, in stead of loosely hanging over the edge of the box). So yes, it's being held up taut by the same thing that's holding it up in the first picture ;) | |
| Apr 26, 2019 at 13:07 | comment | added | noedne | @HansJanssen Or are you suggesting that when you pull one end of the rope, you are still holding the other end taut? | |
| Apr 26, 2019 at 13:02 | comment | added | user29705 | Why the two ropes to the top of the box? The other end of the rope (not being pulled) works just fine combined with the pulley. | |
