Physical pendulum/Bessel pendulum
Physical pendulum/Bessel pendulumThe physical pendulum is used to study moments of inertia and the motion of rigid bodies. The centre of gravity, pivot point and moment of inertia can be varied in innumerable ways. For calculation, Steiner’s theorem is useful, as well as a number of formulae for moments of inertia of the pendulum’s different components.
