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: WebA four-bar linkage has the following dimensions: A0B0-2 in., AoA-2 +收in., AB-1 + ½ in., BDB = 2-3 in. (see Fig. P3.1). (a) Determine the type of four-bar by the Grashof criterion.
