Hi, I'm a bit confused with determining the tension in a rope. For example, when two people are puling on a rope, one with a force F and the other with a force 2F, how can you calculate the tension? I know the tension at any point in a rope is the magnitude of force acting at that point, and that the tension is the same everywhere if the rope is in equilibrum. But I can't figure out what to do next.. I hope someone can help me, since I'm kind of stuck on every physics problem involving tension..
