Why does the rope fly up from the nail against gravity? As shown in the picture, the blue arrow is the nail fixed on the wall, the yellow arrow is the rope, and the green arrow is the iron block. The rope on the right side of the nail moves downward under the action of the iron block, and the rope on the left side of the nail moves upward. At some point, the rope goes up and away from the nail. Why? How to calculate the height away from the nail?
