http://www.me.unlv.edu/~mbt/320/Animation/Grashof.html WebJun 10, 2024 · The Grashof’s law states that for a four-bar linkage system, the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links, then the shortest link can rotate fully with respect to a neighboring link. Consider a four-bar-linkage.
