1. The problem statement, all variables and given/known data A circular disk with a rectangular hole has a radius of 0.620 m and mass of 0.470 kg. It is suspended by a point on its perimeter as shown in the figure. The moment of inertia about this point is I_p = 1.60E-1 kgm2. Its center of mass is located at a distance of s=0.120 m from the center of the circle as shown. If the disk is allowed to oscillate side to side as a pendulum, what is the period of oscillations 2. Relevant equations ω=2∏f f=1/T I_g=1/2mr^2 3. The attempt at a solution I'm lost on this question, any help would be greatly appreciated!
