WebWith reference to the Buckingham Pi Theorem there are 9 – 5 = 4 dimensionless groups. Choose L, k, g and as the reference variables. Thus the groups are as follows:. Solving these groups gives:. From the two groups and the product forms the Grashof number:. Taking and the preceding equation can be rendered as the same result from deriving the … WebGrashof [7] first introduced a very simple rule to judge the rotatability of links in four-bar linkages. Although the problem drew the attention of many researchers [4, 8, 9], the rule, …
