Introduction:
In mechanical power transmission systems, belts are often used to transfer power between two rotating shafts. The efficiency of power transmission depends on the tension in the belt. The maximum power transmission occurs when the total tension in the belt is optimized. This can be achieved by considering the centrifugal tension in the belt.
Explanation:
To understand why the maximum total tension in the belt should be three times the centrifugal tension, we need to consider the different types of tensions acting on the belt during power transmission.
1. Tension in the tight side:
The tight side of the belt experiences tension due to the driving force applied to the belt. This tension is responsible for transmitting power from the driver shaft to the driven shaft.
2. Tension in the slack side:
The slack side of the belt experiences less tension compared to the tight side. This tension is necessary to maintain the belt's position on the pulleys and prevent slippage.
3. Centrifugal tension:
When the belt is in motion, it experiences centrifugal forces due to its own weight. These forces create tension in the belt, which opposes the driving force. The centrifugal tension increases with the speed of the belt.
4. Total tension:
The total tension in the belt is the sum of the tension in the tight side, tension in the slack side, and the centrifugal tension.
Maximizing power transmission:
To maximize power transmission, we need to optimize the tension in the belt. The tension in the tight side and slack side should be balanced to prevent excessive wear and slippage. Additionally, the centrifugal tension should be considered.
When the total tension is twice the centrifugal tension (as mentioned in option A), the belt may experience excessive wear and slippage. This can lead to reduced power transmission efficiency and potential belt failure.
On the other hand, when the total tension is thrice the centrifugal tension (as mentioned in option B), the tension in the belt is balanced, and the centrifugal tension is properly accounted for. This ensures efficient power transmission without excessive wear or slippage.
Therefore, the correct answer is option B - thrice the centrifugal tension.
