A uniform disc of mass m and radius r is suspended through a wire attached to its centre. If the time period of the torsional oscillations be T, what is the torsional constant of the wire?

Moment of inertia about centre of mass of a uniform disc

I =

Time period T = 2π whrere K torsional costant

Therefore K =

= =
