WebGrashof Crank-Rocker. This type of Grashof linkage is obtained when the shortest linkis the input link (r2). The input link has full motion. Theoutput link has a limited range of … Planar quadrilateral linkage, RRRR or 4R linkages have four rotating joints. One link of the chain is usually fixed, and is called the ground link, fixed link, or the frame. The two links connected to the frame are called the grounded links and are generally the input and output links of the system, sometimes called the input link and output link. The last link is the floating link, which is also called …
