The creep in belt drive is due to the:
The creep in belt drive is due to the:
Show Hint
To minimize creep, ensure that the tension on the tight and slack sides of the belt is as equal as possible. This will improve the efficiency and lifespan of the belt drive.

- Material of the pulleys
- Material of the belt
- Unequal size of the pulleys
- Unequal tension on tight side and slack sides of the belt

The Correct Option is D
Solution and Explanation
Creep in a belt drive refers to the relative slipping between the belt and the pulley, which occurs due to uneven tension on the tight and slack sides of the belt. This can lead to inefficient power transmission and wear of the belt.
- Material of the pulleys is not the primary cause of creep. The material of the pulley affects wear but does not cause creep directly.
- Material of the belt also influences the wear and efficiency but is not directly responsible for creep.
- Unequal size of the pulleys does not directly lead to creep; it can cause misalignment but not the tension imbalance that causes creep.
- Unequal tension on tight side and slack sides of the belt is the correct cause of creep. When the tension is different between the two sides, it can cause the belt to slip relative to the pulley, leading to creep.
Thus, the creep in a belt drive is primarily due to unequal tension on the tight and slack sides of the belt.
