SIMPLE HARMONIC MOTION
... A torsion pendulum consists of an object suspended by a wire or thin rod, as in Figure 9-3(c), which undergoes rotational simple harmonic oscillations. From Hooke’s law, the torque t needed to twist the object through an angle q is t = Kq provided the elastic limit is not exceeded, where K is a cons ...
