Analysis:
To understand why option 'B' is the correct answer, let's analyze the situation step by step.
Power Rating:
The motor used in the pulp mill has a power rating of 50 kW. This means that it is designed to deliver a maximum power output of 50 kW.
Number of Belts:
The motor is connected to the load using six V belts. These belts are responsible for transmitting power from the motor to the load.
Continuous Running:
The motor has been running continuously for a month. This implies that the belts have been subjected to continuous stress and wear during this period.
Broken Belt:
One of the belts has broken. This indicates that the belt has reached its maximum load-bearing capacity and has failed under the stress.
Replacement:
Now, let's consider the options for replacing the broken belt.
a) Replace Broken Belt with a Similar Belt:
If we replace only the broken belt with a similar belt, there is a high chance that the newly replaced belt will fail soon. This is because the other belts have been subjected to the same stress and wear as the broken belt. Therefore, this option is not suitable as it does not address the underlying issue of belt wear and stress.
b) Replace all the Belts:
The correct option is to replace all the belts. This is because the belts have been running continuously for a month and are likely to have experienced similar levels of stress and wear. By replacing all the belts, we ensure that the new belts are in good condition and can handle the load effectively. This option addresses the issue of belt wear and stress and ensures the reliable operation of the motor.
c) Replace Broken Belt and Two Adjacent Belts:
Replacing the broken belt and two adjacent belts may seem like a reasonable option. However, this does not guarantee that the remaining belts are in good condition. The two adjacent belts may also have experienced similar levels of stress and wear and may fail soon. Therefore, this option does not provide a comprehensive solution to the problem.
d) Replace Broken Belt and One Adjacent Belt:
Similar to option 'c', replacing the broken belt and one adjacent belt does not ensure the reliability of the remaining belts. The remaining belts may have also reached their maximum load-bearing capacity and may fail soon. Therefore, this option is not the best solution.
Conclusion:
Based on the analysis, option 'B' is the correct answer. By replacing all the belts, we ensure that the new belts are in good condition and can handle the load effectively. This option addresses the issue of belt wear and stress and guarantees the reliable operation of the motor.
