WebDec 4, 2024 · A four-bar chain mechanism has four links and four rotating pairs. The four-bar linkage is a planar mechanism of four rigid members: a frame, an input link, an output link, and a coupler link. Four revolute pairs connect these members, forming a closed-loop kinematic chain with one degree of freedom. WebDec 23, 2024 · Crank Rocker Mechanism. Crank Rocker Mechanism is a four bar linkage. In this linkage, the shortest link rotates fully while the other link pivoted to the fixed link oscillates. It is a Grashof linkage for which the sum of the lengths of the shortest link and the largest link is less than the sum of the lengths of the other two links. how to run sh script in unix
