Homework Equations





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).
