Q90

The centrifugal tension in belts

A.
Decreases the power transmitted
B.
Increases the power transmitted
C.
Increase the wrap angle
D.
Increases the belt tension without increasing power transmission
Answer

Answer: Option D

Solution

Answer: Option D
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.
