Four-Bar Linkage Four-Bar Linkages can be used for non linear motion transmission.9 In a four-bar linkage, Grashof’s Law determines whether there is a link that canrotates 360 degree.• If the sum of length of the longest <strong>and</strong> shortest links are less than the sum oflength of the other two links, there must be a link that can rotate 360 degree.• If not, no link can rotate 360 degree. When Grashof’s Law is satisfied, there are 3 possible mechanisms: crank <strong>and</strong>rocker, double crank, <strong>and</strong> double rocker.
