LINK

Description

The LINK connection constrains the position of node b, $x_{b}$ , to a constant distance from node a. The distance between the two nodes is

l = ∥ x_{b} - x_{a} ∥

and is constant. The constraint force in the LINK connection acts along the line connecting the two nodes and is

\bar{f} = f_{1} q, where q = \frac{1}{∥ x_{b} - x_{a} ∥} (x_{b} - x_{a}) .
