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 … WebAnswer :- s+l≤p+q. As per Grashof’s law, in a four-bar mechanism, the sum of the lengths of the shortest and the longest link should be less than or equal to the sum of the lengths of two remaining links for continuous …
