Difficult# Physical Pendulum: Calculating the Period

APPHMC-BBEC39

The uniform rod shown has a length $1.2\ m$, mass of $2.3\ kg$, and pivots around point P at one end. The rotational inertia of a uniform rod around its endpoint is $\frac { 1 }{ 3 }\ m{ l }^{ 2 }$

What is the period of oscillation for this physical pendulum for small angles of oscillation?
