Belts are suitable for applications beyond which of the following?

Belts are indeed suitable for various applications, but when it comes to high-horsepower machines, they become less effective. In high-horsepower applications, belts may not provide the necessary strength and durability due to the increased tension and stress placed on them. This can lead to slippage, excessive wear, and even failure of the belt, causing operational issues.

High-horsepower machines typically require components that can handle greater forces, such as gears or chains, which provide more robust and reliable power transmission. Therefore, belts are generally more applicable in situations involving smaller horsepower, lower speeds, or those requiring high precision, where the lower strain allows for effective and efficient operation.
