WebGrashof [7] first introduced a very simple rule to judge the rotatability of links in four-bar linkages. Although the problem drew the attention of many researchers [4, 8, 9], the rule, … WebJun 10, 2024 · Grashof’s Law. 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. small business structure flow chart
