Grashof's rule
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.

WebThe Law of Grashof establishes that: In a flat four - bar mechanism articulated with one fixed, at least one of the bars can make a full turn, provided longer the sum of the shortest bar and the bar is less than or equal to the sum of the other two.. There are five flat four-bar or link mechanisms that comply with Grashof's law (An example is shown in Figure 1). 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+lg+h then no bars will rotate through 360°. The two bars attached to the crank can take one of four different types:
WebThe Grashof number is a dimensionless number named after Franz Grashof. The Grashof number is defined as the ratio of the buoyant to a viscous force acting on a fluid in the velocity boundary layer. Its role in … 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
