Four Bar Synthesis for 3 Known Coupler Positions

The synthesis of a four bar mechanism when the coupler link moves to three specific positions. Constructed by hand with a compass and ruler.

Amazing video, I had no clue what we were doing in my lecture when this was shown. Excellent explanation!

[@alexeib2060]

Thanks for the quick explanation, helps a lot!

[@JesusMartinez-zu3xl]

wow!! you made a concept that was very difficult for me into something that is now very easy!

[@hayley9546]

Very helpful and clear, thank you!

What a fucking beast

Thanks u

Just been asking chatgpt how to do this and it gave me names of methods I could google.
I've always had a fascination with geometry but this make me feel there's a whole subject that I've never touched upon. Am I missing some form of mathematics which describes these mechanism and has it's own set of rules for simplifying etc?

poweeeeeeeerful

[@amrnagah3398]

I have a case I want to make the synthesis analysis for the position and design of the mechanism needed to make the movement?!

thank God

thanks bro

Great 👍🏽 👍🏽 👍🏽
It would have been nice to see the tangible proof though 😊
If only the 2 end positions are defined, is there an infinite number of ways it could be accomplished?

Please make video of three and four position synthesis for four bar chain mechanism by inversion method

Hello! Great explenation!
Can you please help me?
I want to make a mechanism that has a long translation(sliding sleeve) and at the end performs a rotation like a flap. I want to make a retractable display for my car and I am out of ideas...
Thanks,

What song is playing in the background?

Parade by Backing Tracks. They opened with this when I saw them in '86, amazing set
