Grashof law for a four bar mechanism
WebGrashof’s law: It states that for a planar four-bar mechanism the sum of shortest and longest link length can’t be greater than the sum of remaining two link length if there has to be continuous relative motion between them. L + S ≤ P + Q (first check this condition then proceed further) WebView 732D518A-EB8A-4850-AE6B-B08EB9197264.jpeg from MEEN 3320 at Lamar University.

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 the mechanism conforms to Grashof's law. For the 4-bar linkage of Figure Q1-2, compute the mechanical advantage given that link 2 (spanning points 1-2) is the driver link. 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.
