At the end of the torsion spring 1 with a coefficient of angular stiffness cφ = 40000 N • m / rad there is a disk 2 with a moment of inertia Iz = 25 kg • m2 relative to the Oz axis. The disk makes angular oscillations around the Oz axis. Determine the angular natural oscillation frequency. (Answer 40)
