Grashof's criterion
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. WebJan 12, 2024 · A 4 revolute pair chain is called the Grashof chain if the following condition is satisfied: l + s . p + q (Class-I four-bar linkage) i.e. the sum of the shortest and longest link should not be greater than the other two. If a Grashof chain with 4 revolute pairs is considered then the following three distinct inversions are possible. Double crank:
