$Kinctic\, energy + potential\, energy = total\, energy$

When kinetic energy is maximum, potential energy
is zero and vice versa.
$Maximum\, potential\, energy = total\, energy.$

$0+K_{0}=K_{0}(\mathrm{K} . \mathrm{E} .+\mathrm{P.E.}=\text { total energy })$

    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 in $N\;m\;rad^{-1}$. (Torsional spring constant $\alpha$ is defined by the relation $J=-\alpha \theta,$ where $J$ is the restoring couple and $\theta$ the angle of twist).
