Pendulum consisting of an actual object allowed to rotate freely around a horizontal axis. Topic: compound pendulum objective: to determine the centre of gravity of a connecting rod, as well as the radius of gyration about the centre of gravity.
Pendulum definition: the pendulum of a clock is a rod with a weight at the end which swings from side to side | meaning, pronunciation, translations and examples. Answer to a compound pendulum consists of a uniform rod of total length l and mass m and a disk of radius r and mass m derive the. In figure 1, you can clearly see that the outer segment (the smallest mass) of the compound pendulum (blue) accelerates relatively slowly to begin with, lagging well behind the rigid pendulum (grey. Consequently, the period of oscillation of a compound pendulum coincides with the period of oscillation of a simple pendulum that has the length l 0 = i/ml this length is called the equivalent length of the given compound pendulum. The compound pendulum a simple pendulum theoretically has the mass of the bob concentrated at one point, but this is impossible to achieve exactly in practice.
