If the sun (S) and the outer ring (R) gears are rotated in the same direction with angular speed $\omega_S$ and $\omega_R$, respectively, then the angular speed of the arm $AB$ is $\dfrac{3}{4} \omega _R + \dfrac{1}{4} \omega _S \\$ $\dfrac{1}{4} \omega _R + \dfrac{3}{4} \omega _S \\$ $\dfrac{1}{2} \omega _R - \dfrac{1}{2} \omega _S \\$ $\dfrac{3}{4} \omega _R - \dfrac{1}{4} \omega _S $ Theory of Machines gateme-2020-set2 theory-of-machines gears-and-gear-trains numerical-answers + – ♦go_editor 448 views answer comment Share Follow Add Sync Questions 0 reply Please log in or register to add a comment.
