A four bar mechanism is composed of four links. if s is the smallest link, l the longest and p,q are the length of the other links. Grashof states that, in order that one of the link is a crank we have to satisfy s+l <= p+q. Solve. WebIn a four-bar linkage, as shown in Fig. 1, Grashof's Law (7, 8) determines whether there is a link that can rotate 360 degree.

WebIn economics, Gresham's law is a monetary principle stating that "bad money drives out good". For example, if there are two forms of commodity money in circulation, which are accepted by law as having similar face value, the more valuable commodity will gradually disappear from circulation.. The law was named in 1860 by economist Henry Dunning … WebInequality (1) is called the Grashof’s criterion or Grashof’s inequality. Paul [13] further proved that the Grashof’s criterion (1) is both necessary and sufficient for the existence of at least one fully-rotatable link in a four-bar linkage. A linkage is called a Grashof linkage if it satisfies the Grashof’s criterion, while it is called a
