Final answer:
The fractional horsepower (FHP) V-belt, also called a light duty belt, is designed for low power applications, typically below 0.5 Hp. It's suitable for small devices and not for high power transmissions.
Step-by-step explanation:
The fractional horsepower (FHP) V-belt, also known as a light duty belt, is specifically designed for low power applications that require less than 1 horsepower. Typically, these belts are suitable for powers below 0.5 Hp. These types of belts are commonly used in domestic or lightweight commercial applications, such as in appliances, small fans, or other low-load mechanical systems. Given that the gain in kinetic energy is a small portion of the energy gain, it is important to note that you should not expect an output of more than about 0.5 hp when using a fractional horsepower belt.
It's important to explain the usage of these belts correctly, as they are not designed to handle industrial-grade high power transmissions. Their construction is tailored to suit the low-power applications they're intended for, thus ensuring efficiency and reliability in those settings.
