1. The problem statement, all variables and given/known data The diagram below shows two people having a tug-of-war. Determine the unknown tension force if person A is winning. http://img80.imageshack.us/img80/8286/forcefp2.gif [Broken] 2. Relevant equations None that I think are necessary. 3. The attempt at a solution I think that the unkown tension for person B would be 900 N, because tension is constant throughout the entire rope.
