WebGrashof's Law. 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. For the four bar linkage Grashof's law provides a simple test for this condition Web• Grashof’slaw is a very important consideration when designing a mechanism driven by a motor. • Grashof’scriteria is used to determine whether or not at least one of the links can rotate 360o. (… in mechanisms driven by motors, helps to ensure that the input crank can make a complete revolution.) Significance of Grashof’sLaw….
