... A rigid object suspended by a wire attached at the top to a fixed support forms such a device. When the object is twisted through some angle Θ, the twisted wire exerts on the object a restoring torque that is proportional to the angular position. So, the torsion τ = -κΘ (κ is torsion constant). (Rea ...
