WebAug 5, 2015 · Grashof's Criteria for Double Crank 4-bar Mechanism The shortest link (S) is the frame which is 400 mm long. The length of the longest link (L) is 1300 mm. The remaining 2 intermediate links (P and Q) have length 700 mm and 1200 mm. This satisfies Grashof's criteria since (S)400 + (L)1300 < (P)700 + (Q)1200. And this is how this …
WebFeb 11, 2024 · Grashof’s Law states that for a four-bar linkage system, if the sum of length of shortest and longest of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links , then the … WebA Grashof linkage is a planar four-bar linkage with s + l p + q where s = length of the shortest link l = length of longest link p and q are the lengths of the two remaining links. For linkages of this type continous relative motion between the shortest link and its adjacent links is possible. Crank-Rocker Double Rocker Rocker-Crank Crank-Crank
