A pendulum is constructed from a thin, rigid, and uniform rodwith a small sphere attached to the end opposite the pivot. Thisarrangement is a good approximation to a simple pendulum (period =5.87 s), because the mass of the sphere (lead) is much greater thanthe mass of the rod (aluminum). When the sphere is removed, thependulum is no longer a simple pendulum, but is then a physicalpendulum. What is the period of the physical pendulum?
