Torsion Pendulum

M.13.4 Torsion Pendulum

The Position of masses on rods can be varied to change the rotational inertia of a torsion pendulum. The period of the pendulum is longer for larger moments of inertia. The torque of the support wire accelerates the rotational motion more slowly when the rotational inertia is large. See illustration W.1.1f.
