Experiment 9: Compound Pendulum
A compound pendulum is a rigid body whose mass is not concentrated at one point and which is capable of oscillating about some xed pivot (axis of rotation). In this experiment we will be studying the behavior of a uniform metallic bar acting as a compound pendulum. The time-period of the oscillations of a uniform bar is governed by the equation ...

Compound Pendulum- Symmetric
The compound bar pendulum AB is suspended by passing a knife edge through the first hole at the end A. The pendulum is pulled aside through a small angle and released, whereupon it oscillates in a vertical plane with a small amplitude. The time for 10 oscillations is measured. From this the period T of oscillation of the pendulum is determined.

B5-1: Determining (g) Using a Compound Pendulum — …
The period of a simple pendulum is T = 2π L g−−√ T = 2 π L g. L is equivalent to the expression 1 h k2 +h2− −−−−−√ 1 h k 2 + h 2, which has a value found graphically as explained in procedure 4 (above). Using this value for L L compute L T2 L T 2, and find g g from the expression: g = 4π2 L T2 g = 4 π 2 L T 2.
