Someone weighs 600N and wants to sit in a basket and pull it up at a constant speed with a pulley block.
The number of rope segments in this topic is 3, but this is consistent with other topics.

In the pulley block, as long as it is a rope that bears the weight of the object, it counts. Ordinary pulley blocks only lift objects, so the rope connected to the moving pulley is also counted. In this topic, people are also promoted, so people are also "heavy objects", so the rope that pulls people is also counted.
