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 ... WebGrashof’sLaw .. for a Planar Four-Bar Linkage … • Grashof’sLaw states that for a planar four-bar linkage system, the sum of the shortest and longest link lengths cannot be greater than the sum of the remaining two link lengths if there is to be a continuous relative rotation between two members. • Mathematically, Suppose
WebNov 6, 2024 · Explanation: According to Grashof’s Law: "A four-bar mechanism has at least one revolving link if the sum of the lengths of the largest and shortest links is less than the sum of lengths of the other two links". The mechanism in which no link makes a complete revolution will not be useful. In a four-bar chain, one of the links, in particular ... WebAug 28, 2014 · Four-bar closed kinematic chain. The first step in the development of Grashof's law consists of forming two pairs with the four bars of the mechanism. The first pair is formed with the bars a and b while the second pair is composed of the bars c and d. That is, each pair is composed with bars that are not adjacent.
