WebCondición Grashof La condición de Grashof para un eslabón de cuatro barras establece: En otras palabras, la condición se cumple si + ≤ + , donde es el enlace más corto, es el más largo y y son los otros enlaces. Clasificación El movimiento de un eslabón cuadrilátero se puede clasificar en ocho casos según las dimensiones de sus cuatro eslabones. WebThe Grashof number can be interpreted physically as a dimensionless number that represents the ratio of the buoyancy forces to the viscous forces in free convection and … 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. fix worn leather
