In order to be of the crank-rocker type, the links have to hrobes Grashof’s law , which states that the sum of the longest and the shortest link must be less than or equal to the sum of the remaining two links.

Up ,to this point the four-bar linkage has been represented as consisting of four lines, Actually, each member is a hroens body which from purely theoretical aspects can be considered as being of indefinite extent figure 6.
