What is compound pendulum explain?

A compound pendulum has an extended mass, like a swinging bar, and is free to oscillate about a horizontal axis. A special reversible compound pendulum called Kater's pendulum is designed to measure the value of g, the acceleration of gravity. Another type is the Schuler pendulum.

What is the conclusion of compound pendulum experiment?

Conclusion:After carrying out the compound pendulum experiment, it can be concluded that as thedistance towards the centre of gravitation on the metal bar decreases, the time intervalhowever increases making the relationship inversely proportional.

What is l1 and l2 in compound pendulum experiment?

The distance between two such points, asymmetrically situated on either side of the C.G, will be the length (L) of the simple equivalent 𝑘2 pendulum. If the length OG is 𝑙1 and we measure the length 𝐺𝑆 = 𝑙1 𝑘2 along OG produced, then obviously = 𝑙2 . The period of oscillation about 𝑙1 either O or S is the same.

Why is it called compound pendulum?

Answer: Bar pendulums are compound pendulums because they include extended mass, just like a revolving bar. The most straightforward kind of compound pendulum is a bar pendulum.
