Which type of power transmission system is likely used if the torque transmitted is high and the speed ratio is 15:1?

In a scenario where the torque transmitted is high and the speed ratio is 15:1, a V-belt is commonly used for its efficiency and capability to handle significant torque loads. V-belts are designed to fit in grooves, allowing them to maintain a high grip and prevent slippage under high torque conditions. They also facilitate the transmission of power between shafts that are not too far apart, which can be advantageous in settings where compact design is essential, alongside the need for a varying speed ratio.

The 15:1 speed ratio indicates a considerable reduction in speed from the driving source to the driven system. V-belts are capable of effectively achieving high gear reductions while still transmitting significant torque, making them suitable for applications in machinery and automotive systems. Their flexibility allows them to adjust dynamically to changing load conditions while maintaining efficient power transfer.

In contrast, while chain drives can also handle high torque, they are typically used in applications requiring a more rigid and durable connection between shafts, and the installation can be more complex compared to V-belts. Spur gears, while excellent for high torque and precise speed ratios, are usually not used for high-speed reductions due to the complexity and cost associated with their design. Flat belts, on the other hand, are more
