Sensitiveness of the governor is defined as the ratio of the

A mean speed to the maximum equilibrium speed
B mean speed to the minimum equilibrium speed
C difference of the maximum and minimum equilibrium speeds to the mean speed
D sum of the maximum and minimum equilibrium speeds to the mean speed

Correct Answer: difference of the maximum and minimum equilibrium speeds to the mean speed

The sensitiveness is defined as the ratio of the difference between the maximum and minimum equilibrium speeds to the mean equilibrium speed.
