torsion pendulum

https://doi.org/10.1351/goldbook.12814
Device consisting of a disc or other body of large moment of inertia mounted on one end of a torsionally flexible elastic rod or wire, the other end of which is fixed.
Note: When the disc is displaced by a (small) angle around its primary rotational axis it will undergo a simple harmonic oscillation after it is released as long as the torque of the rod or the wire is proportional to the torsion angle.
