Rayleigh number. O Grashof number. O Reynolds number. Web1. Consider the 3R-1P mechanism as shown in the figure below. (a) Can we apply Grashof criterion to the mechanism? What is the condition for the mechanism to be a Grashof chain? (b) Let L 2 = 20 cm, L 3 = 25 cm and e = 5 cm. Consider at an instant that the angle θ 2 = 12 0 ∘. Draw the full configuration of the mechanism using a suitable scale.
