WebJan 3, 2024 · Now let’s discuss the Grashof condition. We broke the condition into two parts: 1. s + l < p + q 2. s + l = p + q 1. s + l < p + q … WebIf l + s > p + q (if the sum of the longest and the shortest link lengths is greater than the sum of the lengths of the two intermediate links).; Only double-rocker mechanisms are possible (four different mechanisms, depending on the fixed link). If l + s = p + q the four possible mechanisms in (1) will result.However these mechanisms will suffer from a condition …
