What condition causes the governor spring tension to be greater than the centrifugal force of the flyweights?
Understand the Problem
The question is asking about the conditions under which the governor spring tension exceeds the centrifugal force of the flyweights, indicating a specific scenario related to engine operation.
Answer
When an increased load causes the engine speed to bog down.
The final answer is a) When an increased load causes the engine speed to bog down.
Answer for screen readers
The final answer is a) When an increased load causes the engine speed to bog down.
More Information
When the engine is under increased load, it slows down, causing the centrifugal force on the flyweights to decrease, allowing the spring tension to dominate.
Tips
Do not confuse increased load (causing slow speed) with decreased load (causing high speed). This is a common mistake while analyzing governor operations.
