Determine the four link lengths and the Grashof classification of the mechanism. b. Is it a crank-rocker, a double crank, a double rocker, or a triple rocker? c. Sketch the mechanism with the large red rocker in its two extreme positions. Use the cosine rule to determine the stroke length (total angular motion) of the rocker.
WebMECHANICAL ENGINEERING DEPARTMENT Grashof Rule • Lengths of links: • Longest link-l Shortest link-s Intermediate links – p, q S + l ≤ p + q For continuous relative motion b/w two links • Linkages that obey this inequality (Grashof linkage, also called a Class I kinematic chain) have at least one link that perform complete revolution. 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 …
