Grashof's law for four bar mechanism
WebDec 26, 2024 · I will describe crank rocker mechanism (one complete revolution) and double crank mechanism (two complete revolutions). These four linkages are: 1) Fixed Link or Ground Link (q) 2) Shortest Link or Crank (s) 3) Longest Link or Coupler (l) 4) Remaining Link or Rocker (p) I have explained Grashof's principle on which these linkages work. s … WebIn a four-bar linkage, we refer to the line segment between hinges on a given link as a bar where: s = length of shortest bar. l = length of longest bar. p, q = lengths of intermediate …
