A rope is used in a tug-of-war between two teams of five people each. Both teams are equally strong, so neither team wins. An identical rope is tied to a tree, and the same ten people pull just as hard on the loose end as they did in the contest. In both cases, the people pull steadily with no jerking. Which rope sustains the greater tension (a) the rope tied to the tree or (b) the rope in the tug-of-war, or (c) do the ropes sustain the same tension?
I thought the answer was (c) but according to my book it is not. I don't understand how it can be different. I mean, if people pull the same way both times there is the same maginitude of force in both cases, right? How can it then be different?
