Homework Help: Tension of a rope

  1. Sep 12, 2011 #1
    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?

    I see it now, thanks. I don't know why you called the problem 'tension of a rope', since it is tension in a rod...

    About your attempt: The tension is equal to just the force on one side, since the forces on either side are equal and opposite, their sum is zero. (Note: you must include the centrifugal force in the calculation).
