Question 407Motor Plants - Assistant Engineer

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.
