SUMMARY
The period of oscillations for a circular disk of radius R and uniform density, pivoting about a fixed point on its circumference, is calculated using the formula T = 2π√(R/g). The discussion highlights the necessity of applying the parallel axis theorem to determine the new moment of inertia, as the disk does not undergo uniform circular motion due to the changing angular velocity. The key takeaway is the importance of understanding the dynamics involved in the oscillation of the disk rather than assuming uniform motion.
