I am having trouble puzzling this one out. What I am trying to understand is why the tension of a rope is uniform throughout (even when there is mass). So I have knowledge that tension is in fact not a force (as it is a scalar quantity). You have two people pulling on a rope in opposite directions and the tension in the rope is the sum of the magnitude of the forces. But now we let the rope hang. Assuming uniform mass throughout, is the force equal on each piece of the rope? I'm under the assumption that it doesn't matter if one part of the rope is stronger than another. But what if one segment has more mass, does that change anything? This isn't for homework, but I should probably have an understanding of this by now. Thank you!
