Assertion (A ): In a short centre open-belt drive, an idler pulley is used to maintain the belt tension and to increase the angle of contact on the smaller pulley.   
Reason (R): An idler pulley is free to rotate on its axis and is put on the slack side of the belt. 
  • a)
    Both A and R are individually true and R is the correct explanation of A  
  • b)

Assertion (A ): In a short centre open-belt drive, an idler pulley is ...
Explanation:

Assertion (A):
- In a short centre open-belt drive, an idler pulley is used to maintain the belt tension and to increase the angle of contact on the smaller pulley.

Reason (R):
- An idler pulley is free to rotate on its axis and is put on the slack side of the belt.

Explanation:
- The assertion is true because in a short centre open-belt drive, the idler pulley is used to maintain proper belt tension by applying a force on the slack side of the belt, preventing it from slipping.
- Additionally, the idler pulley also increases the angle of contact on the smaller pulley, which helps in improving the power transmission efficiency.
- The reason is also true as an idler pulley is free to rotate on its axis and is usually placed on the slack side of the belt. This allows the idler pulley to adjust automatically to the belt tension and maintain proper alignment between the pulleys.
- Therefore, both the assertion and reason are individually true, and the reason correctly explains why an idler pulley is used in a short centre open-belt drive.
