Grashof equation
WebThe planar fourbar mechanism is classified according to Grashof's rule. For the practically important crank-rocker mechanism six dependent design parameters are introduced. The relevant constraint equations are derived and discussed. Introduction. A fourbar linkage is the most simple mechanism having a mobility of one and revolute joints only. http://article.sapub.org/10.5923.j.mechanics.20241002.02.html
