Question

Why bar pendulum is called a compound pendulum?

Answer 1

The reason a bar pendulum is called a compound pendulum:

1. The compound pendulum has an extended mass like a swinging bar.
2. The simplest form of the compound pendulum is a bar pendulum.
3. A bar pendulum with holes drilled along its length in equal parts is in the form of a rectangular bar.
4. A metallic bar that is one meter long makes up the bar pendulum. A sequence of circular holes, each measuring about 5 mm in diameter, are bored down the length of the bar.
5. Any hole can accommodate a horizontal knife edge, which suspends the bar.
