[Note 1] However, it is possible to generate a 5-bar cognate using gears. Select four-bar linkage of choice. Construct two parallelograms off of the center coupler link and the links connected to the ground. On each parallelogram, find the sides opposite of the connecting link. Apply a 1:1 gear train between them. Separate cognates. The ...
The coupler (link 3) point stays within 1% positional tolerance while intersecting the ideal straight line 6 times. The linkage was first shown in Paris on the Exposition Universelle (1878) as "The Plantigrade Machine". [5] [3] The Chebyshev Lambda Linkage is a cognate linkage of the Chebyshev linkage.

Link 1 (distance between ground joints): 2a. In kinematics, the Hoecken linkage (named for Karl Hoecken) [1] is a four-bar linkage that converts rotational motion to approximate straight-line motion. The Hoecken linkage is a cognate linkage of the Chebyshev linkage and Chebyshev's Lambda Mechanism. The linkage was first published in 1926. [2] [3]
Cognate object, a verb's object that is etymologically related to the verb; Cognate (kinship), person who shares a common ancestor; Cognate linkage, a kinematic linkage that generates the same coupler curve as another linkage of a different geometry; Cognate interaction, in immunology denotes the specific, contact-dependent interaction between ...
This linkage is an ester bond that chemically binds the carboxyl group of an amino acid to the terminal 3'-OH group of its cognate tRNA. [7] It has been discovered that the amino acid moiety of a given aa-tRNA provides for its structural integrity; the tRNA moiety dictates, for the most part, how and when the amino acid will be incorporated ...
The official 2007 edition of the UCC. The Uniform Commercial Code (UCC), first published in 1952, is one of a number of uniform acts that have been established as law with the goal of harmonizing the laws of sales and other commercial transactions across the United States through UCC adoption by all 50 states, the District of Columbia, and the Territories of the United States.
Link 1 (horizontal distance between ground joints): 4a Illustration of the limits. In kinematics, Chebyshev's linkage is a four-bar linkage that converts rotational motion to approximate linear motion. It was invented by the 19th-century mathematician Pafnuty Chebyshev, who studied theoretical problems in kinematic mechanisms.
