WebA four-bar linkage, also called a four-bar, is the simplest movable closed-chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. What are the four types of linkages? WebDec 26, 2024 · 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 …
