WebAccording to Grashof’s law a four-bar linkage framework, the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links, then the shortest link can rotate fully with respect to an adjoining link. WebThe role played by Reynolds number in forced convection is played by the Grashof number in natural convection. The critical Grashof number is observed to be about 109 for vertical plates. Thus, the flow regime on a vertical plate becomes turbulent at Grashof number greater than 109. The heat transfer rate in natural convection is expressed by
WebMay 26, 2024 · The Grashof condition compares s+l to g+h where s is the shortest length, l is the longest and g, h are the other two lengths. If s+l < g+h then at least one of the bars will rotate through 360°. If s+l > g+h then no bars will rotate through 360°. The two bars attached to the crank can take one of four different types: WebGrashof’s rule states that for a planar crank-rocker four bar mechanism, the sum of the shortest and longest link lengths cannot be less than the sum of the remaining two link lengths; Inversions of a mechanism are created by fixing different links one at a time.

When designing a linkage where the input linkage is continuously rotated e.g. driven by a motor it is important that the input link can freely rotate through complete revolutions. The arrangement would not work if the linkage locks at any point.
