A mass of 15 kg is tied at the end of a steel wire of the length lm. It is whirled in a vertical plane with angular velocity 1 rad/s. Cross sectional area of the wire is 0.06 cm^(2). Calculate the elongation of the wire when the mass is at its lowest position. Y_("steel”) = 2 xx 10 ^(11) Nm ^(-2)

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 a is defined by the relation J = –alphatheta , where J is the restoring couple and q the angle of twist).
