For $${{\omega _1} = 60}$$ rpm clockwise $$(CW)$$ when looked from the left, what is the angular velocity of the carrier and its direction so that Gear $$4$$ rotates in counter clockwise $$(CCW)$$ direction at twice the angular velocity of Gear $$1$$ when looked from the left?

$$130$$ rpm, $$CW$$

$$223$$ rpm, $$CCW$$

$$256$$ rpm, $$CW$$

GATE ME 2006 Theory of Machines - Gears and Gear Trains Question 17 English

What is the relation between the angular velocities of Gear $$1$$ and Gear $$4$$?

$${{{\omega _1} - {\omega _5}} \over {{\omega _4} - {\omega _5}}} = 6$$

$${{{\omega _4} - {\omega _6}} \over {{\omega _1} - {\omega _5}}} = 6$$

$${{{\omega _1} - {\omega _2}} \over {{\omega _4} - {\omega _5}}} = - \left( {{2 \over 3}} \right)$$

$${{{\omega _2} - {\omega _5}} \over {{\omega _4} - {\omega _5}}} = - \left( {{8 \over 9}} \right)$$
