What condition causes the governor spring tension to be greater than the centrifugal force of the flyweights?
Understand the Problem
The question is asking which condition leads to the governor spring tension surpassing the centrifugal force of the flyweights. This involves understanding the operation of a governor in mechanical systems, particularly how load and engine speed interact.
Answer
(a) 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.

The final answer is (a) When an increased load causes the engine speed to bog down.
More Information
When the load on an engine increases, the engine speed decreases if not compensated. This reduces the centrifugal force on the flyweights, allowing the governor spring to exert more force, maintaining the speed by adjusting fuel intake or blade pitch.
Tips
A common mistake is assuming constant speed or idle conditions will increase spring tension. These conditions typically maintain or reduce spring tension relative to flyweights.
