Which of the following statement is wrong ?a)The power transmitted by ...
The correct statement is option 'B' - "The V-belt drive is used with large centre distance" is wrong.
V-belt drives are typically used when the center distance between the driving and driven pulleys is relatively small. This is because V-belts are designed to transmit power efficiently over short distances. When the center distance is large, other types of belt drives such as flat belts or timing belts are more suitable.
Let's break down the incorrect statement and explain why it is wrong:
1. The power transmitted by V-belts is less than flat belts for the same coefficient of friction, arc of contact, and allowable tension in the belts.
- This statement is true. V-belts have a smaller contact surface area compared to flat belts, which results in a lower power transmission capability. The V-belt's shape allows for higher tension in the belt, which helps improve power transmission efficiency.
2. The V-belt may be operated in either direction with the tight side of the belt at the top or bottom.
- This statement is true. V-belts can be used in either direction, and the tight side of the belt can be positioned at the top or bottom depending on the application requirements.
3. The ratio of driving tensions in V-belt drive is more than flat belt drives.
- This statement is true. V-belt drives have a higher ratio of driving tensions compared to flat belt drives. The V-belt's shape and design allow for higher tension levels, which helps prevent slip and ensure efficient power transmission.
To summarize, the correct statement is option 'B' - The V-belt drive is used with large center distance. V-belt drives are more suitable for shorter center distances, and other belt types are preferred for larger center distances.
