Fourbar 3 Precision Points Synthesis Solution ( 2 of 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. The three points are P1(30,5), P2(15,15), P3(5,30). Using the arbitrary free choices we used in the synthesis process, the resulting fourbar mechanism is a crank-rocker (Non-Grashof). This example demonstrate that with this dyadic synthesis method, there is no guarantee on the type of mechanism (Grashof or Non-Grashof) you will get. There is also no guarantee that the mechanism will pass through all 3 points in one configuration (crossed/ uncrossed). The resulting fourbar mechanism is a crank-rocker. This is the simulation where the crank (R2) rotate 360 degree with crossed configuration. In this configuration, the mechanism is able to pass through the remaining two points. The uncrossed configuration pass through the remaining one point - please see part 1 of this video here: "Fourbar 3 Precision Points Synthesis Solution ( 1 of 2 )" http://www.youtube.com/watch?v=SJiYLvzhaow Note: The first version of this video have a wrong title in the simulation - instead of "Fourbar Synthesis: 3 Precision Points", it was "Limiting Position: Fourbar (Crank-Rocker)". This version updated this error. The first version of this simulation can be found here: http://www.youtube.com/watch?v=JXi4UqNTboo 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.
