Due to clogging of chain rings with mud, actual length of the chain will become less than nominal length of chain. Therefore, measured value is greater than true value.
Error in measurement = Measured value – True value

Which type of errors introduces due to clogging of chain rings with mu...
Clogging of chain rings with mud can introduce positive errors.
Explanation:
When the chain rings of a vehicle get clogged with mud, it can lead to an increase in the effective diameter of the chain rings. This increase in diameter causes the chain rings to rotate at a slightly higher speed than they would under normal conditions. As a result, the distance covered by the vehicle will be measured as greater than the actual distance traveled. This discrepancy between the measured and actual distance is known as a positive error.
To understand this in more detail, let's break down the concept:
1. What are chain rings?
- Chain rings are toothed wheels that are connected to the axle of a vehicle and are used to measure distance traveled.
2. How does the clogging of chain rings with mud cause errors?
- When the chain rings get clogged with mud, the mud accumulates between the teeth of the chain rings, effectively increasing their diameter.
- A larger diameter of the chain rings results in the wheels rotating at a slightly higher speed than they would under normal conditions.
- The increase in rotational speed leads to the measurement of a longer distance traveled than the actual distance covered.
3. What are positive errors?
- Positive errors occur when the measured value is greater than the actual value.
- In the case of clogging of chain rings with mud, the increase in diameter of the chain rings causes the wheels to rotate faster, resulting in a measurement of a longer distance traveled.
Conclusion:
In summary, the clogging of chain rings with mud introduces positive errors because it leads to an increase in the effective diameter of the chain rings, causing the wheels to rotate at a higher speed and resulting in a measurement of a longer distance traveled than the actual distance.
