Question 407Motor Plants - Assistant Engineer
70% to passThe governor, shown in the illustration, will have its preset speed droop altered whenever_______________. Illustration MO-0092
Athe compensating lever fulcrum is changed
Bthe speed droop lever fulcrum is changed
Cthe speeder spring tension is changed
Dall of the above
AI Explanation
The correct answer is B) the speed droop lever fulcrum is changed. The speed droop of a governor is the reduction in speed that occurs as the load on the engine increases. The speed droop lever fulcrum determines the amount of speed droop, so changing the position of this fulcrum will alter the preset speed droop of the governor. The other options are incorrect because changing the compensating lever fulcrum or the speeder spring tension would not directly affect the preset speed droop - these adjustments would impact other governor characteristics rather than the speed droop specifically.
