In a four-bar linkage, we refer to the line segment between hinges on a given link as a bar where: s = length of shortest bar. l = length of longest bar. p, q = lengths of intermediate bar.

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. One link of the chain is usually fixed, and is called the ground link, fixed link, or the frame. The two links … See more The synthesis, or design, of four-bar mechanisms is important when aiming to produce a desired output motion for a specific input motion. In order to minimize cost and maximize efficiency, a designer will choose the simplest mechanism possible to … See more • Burmester's theory • Cognate linkage • Five-bar linkage • Kinematic synthesis See more http://www.mechanicalwalkins.com/grashofs-law-condition-and-different-mechanism/
