In a Hartnell governor, the lift of the sleeve is given by (where r1 and r2 = Max. and Min. radii of rotation, x = Length of ball arm of the lever and y = Length of sleeve arm of the lever)
A. $$\left( {{{\text{r}}_1} + {{\text{r}}_2}} \right)\frac{{\text{y}}}{{\text{x}}}$$
B. $$\left( {{{\text{r}}_1} + {{\text{r}}_2}} \right)\frac{{\text{x}}}{{\text{y}}}$$
C. $$\left( {{{\text{r}}_1} - {{\text{r}}_2}} \right)\frac{{\text{y}}}{{\text{x}}}$$
D. $$\left( {{{\text{r}}_1} - {{\text{r}}_2}} \right)\frac{{\text{x}}}{{\text{y}}}$$
