WebDec 19, 2024 · The mechanism in which no link makes a complete revolution will not be useful. In a 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 Grashof ’s law. Such a link is known as a crank or driver i.e. AD (link 4 ) is a crank.
