Fourbar 3 Precision Points Synthesis Solution ( 1 of 2 ) - Video

Tutorial Description
The resulting fourbar mechanism from a dyadic synthesis. 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). This is the simulation where the crank (R2) rotate 360 degree with uncrossed configuration. In this configuration, the mechanism is able to pass through the only one points. The crossed configuration pass through the remaining two points - please see part 2 of this video: "Fourbar 3 Precision Points Synthesis Solution ( 2 of 2 )" http://www.youtube.com/watch?v=9Beymhbu-mM 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=DqFcG_h15x8 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.
