Cold flow of the flex hose were caused by: A. Under torque B. Over torque C. Vibration
Understand the Problem
The question is asking about the cause of cold flow in flex hoses, providing multiple-choice answers related to torque and vibration. This implies an inquiry into engineering or material science.
Answer
Over torque
Cold flow of the flex hose is generally caused by over torque.
Answer for screen readers
Cold flow of the flex hose is generally caused by over torque.
More Information
Cold flow in flexible hoses occurs when there is excessive pressure applied to the hose material during installation or operation, often due to over torque. Over time, this can cause the material to decompose slowly, producing a loss of integrity.
Tips
A common mistake is assuming that vibration would cause cold flow, but vibration typically results in other types of damage such as chafing or surface wear.
