A uniform disc of radius 5.0 cm and mass 200g is fixed at its centre to a metal wire, the other end of which is fixed with a clamp. The hanging disc is rotated about the wire through an angle and is released. If the disc makes torsional oscillations with time period 0.20s, find the torsional constant of the wire.

A uniform of radius 5.0 cm and mass 200 g is fixed at its centre to a matel wire , the other end of which is fixed to a celling. The hanging dise is rotate obout the wire through an angle and is released. If the dise makes torsional oscillations with time period 0.20 s , find the torsional constant of the wire.

A circular disc fixed at its centre to a metal wire and the other end of the wire is clamped. The disc is rotated about the wire as axis and is released. The disc about this axis makes simple harmonic oscillations with a frequency of (1)/(2) Hz. If moment of inertia of the disc about this axis is 0.1 kg -m^(2) , the torsional constant of the wire is

A circular disc of mass 12 kg is suspended by a wire attached to its centre. The wire is twisted by rotating the disc and then released, so that the time period of torsional oscillation is 2 s. If the radius of the disc is 10 cm, then calculate the torsional spring constant of the wire.

A circular disc of mass 10 kg is suspended by a wire attached to its centre. The wire is twisted by rotating the disc and released. The period of torsional oscillations is found to be 1.5 s. The radius of the disc is 15 cm. Determine the torsional spring constant of the wire. (Torsional spring constant alpha is defined by the relation J = -alphatheta , where J is the restoring couple and 0 the angle of twist).
