1. The problem statement, all variables and given/known data A piece of string of length l and mass M is fastened into a circular loop and set spinning about the center of a circle with uniform angular velocity omega. Find the tension in the string. Suggestion: Draw a force diagram for a small piece of the loop subtending a small angle delta theta. 2. Relevant equations 3. The attempt at a solution I know I'm supposed to use differentials and then integrate, but isn't the tension in the rope the same everywhere?
