1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution I don't know how to find Tension (T). I think the Tension contains 2 parts. First part is the rod near the center, it exerts a force on P toward the center. Second part is on the other side of the rod, which exerts a force on P away from the center. Is the Tension equals the sum of the 2 force?
