Question 4

PQRS is the 4 bar mechanism as shown below where PQ = 300 mm RS = 600 mm link PS is fixed,PQ = 5 rad/s. velocity of R at instant shown in figure is____ m/sec?


Question 5

In an epicyclic gear train, shown in the figure, the outer ring gear is fixed, while the sun gear rotates counterclockwise at 100rpm. Let the number of teeth on the sun, planet and outer gears to be 50, 25, and 100, respectively. The ratio of magnitudes of angular velocity of the planet gear to the angular velocity of the carrier arm is _________.

Question 6
