1. The problem statement, all variables and given/known data A uniform circular disk whose radius R is 14.3 cm is suspended as a physical pendulum from a point on its rim. (a) What is its period? (b) At what radial distance r < R is there a pivot point that gives the same period? (give answer in cm) 2. Relevant equations T= 2pi radical ( I / mgh ) 3. The attempt at a solution Okay, I already found part A using T= 2pi radical ( I / mgh ) Any help would be greatly appreciated =] Part A: 0.849 s <-- It's correct. I'm just stuck on Part B.
