Case 3: The shortest link is opposite to the fixed … Web- Double rocker, provided that the shortest bar is opposite the fixed one. When the equality is fulfilled in Grashof's formula, then we are in the limiting case in which the sum of the shortest bar with the longest bars is equal to the sum of the other two. In this case, the mechanism can adopt a configuration in which the four bars are aligned.
