Four bar chain problem statement

WebFeb 11, 2024 · In a four bar chain there are four turning pairs and no sliding pairs. Let denote the smallest link of four bar linkage with S and the longest link by L and the other two links by P and Q. The necessary condition to satisfy Grashof’s Law is : S + L ≤ P + Q This condition is divided into two cases :- 1) S + L < P + Q 2) S + L = P + Q WebThe four-bar linkage is a planar mechanism consisting of four rigid members: the frame, the input link, the output link, and the coupler link. These members are connected by four revolute pairs forming a closed-loop kinematic chain of 1-degree-of-freedom. A point on the coupler, known as the coupler point, traces a path as the input link is ...
