Grashof's criterion
WebJan 12, 2024 · According to Grashof’s Law: "A four-bar mechanism has at least one revolving link if the sum of the lengths of the largest and shortest links is less than the sum of lengths of the other two links". The mechanism in which no link makes a complete revolution will not be useful. WebGrashof’s criterion defines the mobility of four-link closed chain mechanisms in relation to its link lengths. A simple assumption can convert a three-link serial manipulator into a four-link ...

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. (b) Determine the range of motion of this linkage if link 2 is the input. (e) Determine the range of motion of this linkage iflink 4 is the input.
