Articulated Mechanisms ' Basis. The Four Bar Linkage

We're going to establish several forms of the linking equation. To do this, we'll use figures 8 and 9 , which show auxiliary parameters linked to the main parameters. These two figures correspond to two forms of the same mechanism. In both cases, the bars are identical. Let's set up the mechanism. To do this, let's assign a value to angle j. Point A is fixed. Point B is at the intersection of the circle centered at A and of radius r and the circle...
