The Grashof Condition

WebJul 6, 2016 · Grashof Condition. A fourbar is considered to be Grashof if the shortest link can rotate fully with respect to a neighboring link. This is determined to be true by comparing the linkage lengths in the following equation: Where S is the shortest link, L is the longest,and P and Q are the remaining two links. http://www.u.arizona.edu/~pen/ame352/Notes%20PDF/1%20Fundamentals.pdf how to set up a breakfast club
