Current Attempt in Progress

A flat uniform circular disk has a mass of $2\mathrm{.}84$ kg and a radius of $52\mathrm{.}9$ cm $.$ It is suspended in a horizontal plane by vertical wire attached to its center. If the disk is rotated $2\mathrm{.}73$ rad about the wire, a torque of $0\mathrm{.}0187N*m$ is required to maintain that orientation. Calculate $($a$)$ the rotational inertia of the disk about the wire, $($b$)$ the torsion constant, and $($c$)$ the angular frequency of this torsion pendulum when it is set oscillating.
