Grashof law for a four bar mechanism
WebThe Grashof condition for a four-bar linkage states: If the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two … WebThe mechanism in which no link makes a complete revolution will not be useful. In four bar chain ,one of the links, in particular the shortest link, will make a complete revolution relative to the other three links,if it satisfies the Grashof’s law. Such a link is known as crank and driver. In fig.4, AD (link 4) is a crank.
