Fourbar 3 Precision Points Synthesis, Fixed Pivot (2/2) - Video

Tutorial Description
The resulting fourbar mechanism from a dyadic synthesis. The task is to synthesize a fourbar mechanism that will pass through three precision points using dyadic synthesis method. In addition, we want to fix the pivoting location of the fourbar mechanism at (-15,-10) & (5,-10). The three points are P1(30,5), P2(15,15), P3(5,30). The resulting fourbar mechanism is a crank-rocker. This is the simulation where the crank (R4) rotate 360 degree with crossed configuration. In this configuration, the mechanism is able to pass through all three points. The crossed configuration pass through all three points - please see part 1 of this video, where the uncrossed configuration only pass through one points: "Fourbar 3 Precision Points Synthesis, Fixed Pivot (1/2)" http://www.youtube.com/watch?v=-kNuOKEz4WA This is an example used in the Dyadic Synthesis in MAE412/512 Machines and Mechanism II class at the State University of New York at Buffalo, Mechanical & Aerospace Engineering Department.
