WebThe present author therefore gives a new demonstration of Grashof's rules which clearly brings out the following points: (1) there are two distinct types of double-rockers, and therefore four ... WebAnswer :- s+l≤p+q. As per Grashof’s law, in a four-bar mechanism, the sum of the lengths of the shortest and the longest link should be less than or equal to the sum of the lengths of two remaining links for continuous relative motion between them. Hence, s+l≤p+q. In the case of Grashof’s law is not truly satisfied, no link will make a ...
The crank–rocker mechanism is, basically, a four-bar mechanism in which the output link oscillates when the input link completely rotates, consistent with Grashof’s Law.
