[#510] The centrifugal tension in belts
Correct Answer

(D) Increases the belt tension without increasing power transmission

Explanation

Solution: The centrifugal tension in belts increases the belt tension without increasing power transmission . Key Points: Centrifugal Tension: This tension is caused by the rotation of the belt and acts to stretch it. Effect: While it increases the overall belt tension, it does not contribute to the power transmitted between the driving and driven pulleys. Impact on Power Transmission: The centrifugal tension can reduce the effective tension available for power transmission because it adds to the total belt tension, which can affect the belt’s grip and efficiency.
