I am reading in my textbook an example problem. In this problem, there is a rope tied to a boulder on one end, and on the other it is tied to a car stuck in the mud. A person then applies a force at the midpoint of the rope. I was wondering if someone could explain to me why the "person pushing on the rope was able to magnify their effort almost six times using this technique"? I ask, because the author didn't do an actual good job at explaining the physics behind this technique, but rather employed themselves in explaining the mathematics--which is the part I don't really have any trouble with. I was just wondering if someone could explain this technique from a conceptual standpoint.
