Question: Design a four bar Grashof crank-rocker for 90 degree of output motion with no quick return. Make the length of the rocker 3 inches. 1) Show the toggle positions. 2) Determine the minimum transmission angle using hand plots and mathematics. WebAsk an expert. Question: Discuss this main question: Where would this mechanism appear in industry? Consider these concepts as you answer and discuss this mechanism - What Grashof classification does this mechanism have? (Use Table 1.2 of the book) What does that tell us about the movement of the links? In other words, do the crank and rocker ...

Grashof condition. The Grashof condition for a four-bar linkage states: If the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links, then the shortest link can rotate fully with respect to a neighboring link. See more In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed-chain movable linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the … See more Planar four-bar linkages are constructed from four links connected in a loop by four one-degree-of-freedom joints. A joint may be either a revolute joint – also known as a pin joint or hinged joint – denoted by R, or a prismatic joint – also known as a sliding pair – denoted by P. See more A slider-crank linkage is a four-bar linkage with three revolute joints and one prismatic, or sliding, joint. The rotation of the See more If the linkage has four hinged joints with axes angled to intersect in a single point, then the links move on concentric spheres and the assembly … See more Planar quadrilateral linkage, RRRR or 4R linkages have four rotating joints.
