Which statement about round belts is true?

Round belts are known for their flexibility and ability to allow twisting, which is essential in certain applications where the belts need to navigate around pulleys or other obstacles without losing efficiency. This flexibility makes them suitable for applications where the direction of movement may change frequently.

In contrast, round belts are generally not designed for high power applications since they typically do not provide the same level of power transmission as other types of belts, such as V-belts. While they can offer some grip, they are not primarily designed to provide high friction; instead, they rely on their flexibility and geometry to work effectively. Additionally, round belts are not exclusive to outdoor equipment; they find use in various applications, both indoors and outdoors.
