Grashof law for a four bar mechanism

WebFor the 4-bar linkage of Figure Q1-2, assume that link 4 can be shortened and extended like a linear actuator. Determine the link 4 (spanning points 3-4) length ranges for which … 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.
