Questions 1. A cylinder of a mass 0.5 kg and diameter 0.1 m is suspended by a wire from its center. When the wire is twisted and released, the cylinder oscillates. Find the period of these oscillations if the torsion constant of the wire is K = 0.85 N . m/rad . 2. An irregular object is suspended by a wire from its center. When a torque of 0.14 N . m is applied to the object, it turns through an angle 0.15 rad, and when it is released, it oscillates with a period of 1.2 s. Find the moment of inertia of the object
