A Cavendish apparatus is shown in in the figure below. You can
estimate the angle of rotation of the rod in the following way.
Assume that the rod is massless, that there is no resistance to
rotation, and that the same force acts on both masses. Then the
acceleration of each mass may be computed independently, using
Newton's second law. Furthermore, if the distance each mass moves
is small compared with the separation between m and
M, then the acceleration...

QUESTION: You are given a meterstick and asked to drill a small hole through it so that, when the stick is pivoted about a horizontal axis through the hole, the period of the pendulum will be a minimum. Where should you drill the hole?(give the distance from the end of the meterstick) Hint: The rotational inertia I of the pendulum can be calculated using the parallel axis theorem.
